Enphase iq7 review

Enphase is one of the biggest names in solar inverter technology, and in the company announced its foray into energy storage with the Enphase Encharge. The Enphase Encharge pairs well with solar panel systems, especially if your utility has reduced or removed net metering, time-of-use ratesor demand charges. Installing a storage solution like the Enphase Encharge with a solar energy system allows you to maintain a sustained power supply during the day or night, as long as you store enough power from your panels when the sun is shining.

As with other battery products, the Enphase Encharge is sized for day-to-day use at your home and is often paired with a home solar panel system. When your solar panels produce more electricity than you can use in your home, you can store the excess electricity in the battery system instead of sending it back into the grid.

When evaluating solar batteries like the Encharge, there are various important metrics and technical specifications to keep in mind. Among the most important are the size of the battery power and capacityits chemistrydepth of dischargeand roundtrip efficiency.

The Enphase Encharge comes in two different sizes with different power and usable capacities. Power measured in kilowatts, or kW determines the maximum amount of electricity that can be output at a single time, while usable capacity measured in kilowatt-hours, or kWh is a measure of the maximum amount of electricity from your battery on a full charge.

The Encharge system is also, to an extent, modular, meaning you can add multiple battery products to your storage setup. For example, you might want to install one Encharge 10 and an extra Encharge 3 to boost your total storage capacity for larger properties with higher electricity needs.

Think of your battery like water running through a pipe. Energy capacity is the amount of water available to push through the pipe, while power is the size of the pipe itself. Larger pipes allow more water to flow through at once, which depletes the water faster. Similarly, a battery with a high power rating can deliver more electricity at one time, but will burn through its available energy capacity faster too.

Batteries with a higher power rating are capable of powering more robust appliances or many appliances at once, while batteries with a higher usable capacity can store more total energy and thus can run your appliances for longer periods of time without needing to recharge. The functionality of one solar battery next to another can vary; some batteries boast of superior off-grid capabilities, while others offer software solutions for rate arbitrage.

Here are some of the most important qualities of the Enphase Encharge:. The Enphase Encharge is an AC-coupled battery ; this means that in a solar-plus-storage system, direct current DC electricity flows from solar panels to a solar inverter that transforms the electricity into alternating current AC electricity. That AC electricity can then flow to your home appliances, or go to another inverter that transforms the electricity back to DC for storing in a battery system.

The Enphase Encharge comes with backup power capabilities. Most solar batteries require an external transfer switch to allow for off-grid operation; however, Enphase offers a product called the Enpower smart switchwhich is designed for installation with your Enphase battery system.

This component connects your home, the grid, your storage, and your solar energy system all together so that the Enphase Encharge system can automatically power your home appliances when the grid goes down. The Enphase Encharge is a lithium-ion storage product; specifically, it is a lithium iron phosphate LFP battery. Relative to other types of batteries, LFP batteries are known for their high power rating and safety — to learn more about how different lithium-ion battery chemistries stack up against one another, check out our overview of battery chemistry differences.

Two key ways to evaluate the performance of a solar battery are its depth of discharge and roundtrip efficiency. Because the useful life of a battery decreases each time you charge, discharge, and re-charge it, many battery manufacturers specify a maximum DoD level for optimal battery performance. In general, batteries with a higher depth of discharge are considered higher quality products. The Enphase Encharge line of storage products boasts a depth of discharge of percent across all battery sizes, reflective of its safe and advanced LFP battery chemistry.Q cables are available in single-phase 2 wire and three-phase 4 wire configuration, with connector spacing for portrait as well as landscape cell and landscape cell module layouts.

All Q cables are now rated at 25 amps. Three-phase circuit sizing Three-phase Q Relays are rated at 25 amps. A 25A circuit breaker must be installed upstream to protect the Q Relay and the solar circuit may terminate directly into the PV terminals of the Q Relay, keeping in mind that the Q Relay terminals are suitable for cables up to 6mm2. Single-phase circuit sizing Single-phase Q Relays are rated at 20 amps.

The data sheet for these relays can be found here. So although the single-phase Q Cable is rated at 25 amps, the 20A Q relays are the limiting factor in single-phase circuits. The single-phase Q Relay must be protected upstream by a 20A circuit breaker. If more than these numbers of modules are required, additional Q relays and branch circuits must be installed. Three-phase Q Relays rated at 25A can be configured during commissioning for single-phase or two-phase operation.

So theoretically a three-phase relay could be used in a single-phase application to enable the full 25A rating of the Q Cable to be utilised, but there are cost and space disadvantages to this approach.

Three-phase Q Relays cost approximately twice as much as a single-phase Q Relay and take up 6 DIN spaces compared to 3 for the single-phase relay In special cases where using the 25A Q relay could alleviate the need for a second circuit having to be run to the roof, this option may be justified.

It is important to note that the three phase Q relay can not be used to switch more than one single phase circuit. Whilst Enphase provide specific guidance around component ratings and recommended number of microinverters per circuit, installers should keep in mind at all times that installations must always comply with all of the regular AS requirements for circuit protection, cable selection, cable joins, voltage drop etc.

How was the score for the Enphase IQ7 calculated? And they charge too much for the app. Even though the salesman said I wood be able to do that. Further advanced insight can only be achieved through purchasing the Enlighten Manager subscription. Approximately 15 months ago I had a 5. I am now increasing with a new additional system of 4. When I purchased my original system, I was advised that this system is the best micro invertor Enphase system available.

Now, I am told that my original micro Enphase system is obsolete and I need to upgrade to the new micro invertors at a premium cost.

As I am using a different supplier to install my additional Enphase system, what interface issues will I experience in interfacing with my original system? How can I have access to observe the individual performance of each solar panels with these two separate systems?Even though microinverters are a very different concept from string inverter technology, many consumers will still compare the Enphase IQ7 microinverter against a string inverter in their buying decision.

For our full disclaimer and further information, see our Terms of Use and our Review Guidelines. Enphase Energy is a US-headquartered manufacturer specialising in the development of microinverters for the solar market. Microinverters are miniaturised inverters that work on a per-panel level. It's a very different approach to a single string inverter working with multiple solar panels, as is more commonly the case with solar power system installations. Given their panel level operation, Enphase microinverters offer a number of advantages over string inverters, including redundancy, more flexible system design, monitoring of individual panels and mitigating the overall impact on a system of solar panel shading.

However, be prepared to pay a bit more for a microinverter-based system. The company's seventh generation microinverter, the Enphase IQ 7 series, is suited to residential applications and commercial systems. With around 17 million units all told shipped to date, Enphase Energy is widely considered as the global leader in microinverter technology.

The company has cultivated a solid international profile thanks to offices located in different areas of the world, including France, Italy, the United Kingdom and China.

Here in Australia, Enphase serves local customers and provides technical and commercial assistance via its office located in Melbourne or, for our visitors from New Zealand, in Christchurch.

About Enphase, Solar Inverters. What does this mean? Enphase Customer Service: 03 Enphase Energy is a US-headquartered manufacturer specialising in the development of microinverters for the solar market.However, more than half of new residential solar installations are using module-level power electronics MLPEs like power optimizers and microinverters to maximize electricity production.

According to Greentech Mediathe two companies controlled 95 percent of the module-level power electronics market in They are also currently the two leading inverter brands featured in quotes to solar shoppers on the EnergySage Solar Marketplace. The question of which is the best solar inverter comes down to cost, performance, warranties, and personal preference. SolarEdge Technologies is headquartered in Israel and manufactures the leading power optimizer product available in the United States.

Unlike microinverters, SolarEdge power optimizers cannot fulfill the function of an inverter alone. Instead, they fix the voltage of the solar electricity and then send it to a centralized inverter to be converted to AC power, which increases the overall efficiency of the system.

According to SolarEdge, there is little difference in efficiency between a system with microinverters and one with power optimizers and a string inverter. A system that uses power optimizers will cost less than one with microinverters, all other things being equal. SolarEdge power optimizers offer many of the same capabilities that Enphase and other microinverter manufacturers do.

SolarEdge also offers the advantage of manufacturing inverters that are compatible with the Tesla Powerwall 2. SolarEdge power optimizers come with a year warranty. Importantly, SolarEdge offers an extended warranty of up to 20 or 25 years for their string inverter system, depending on the model. This extension comes at an additional cost. Enphase is headquartered in California and manufactures the most popular microinverter product for sale in the United States today.

Like power optimizers, microinverters are located on the roof alongside individual solar panels. Instead of sending electricity to a centralized string inverter, systems with microinverters convert the DC solar electricity to useful AC electricity at the site of the solar panel. Generally speaking, a solar panel system with microinverters will be slightly more efficient than one with power optimizers. However, up-front costs and maintenance costs will be higher with Enphase microinverters than with SolarEdge power optimizers due to the fact that that microinverters are a more technologically complex piece of equipment.

Enphase also manufactures a storage product that can be used in conjunction with its microinverters. The company was founded in and is considered widely considered to be a manufacturer of high-quality inverter products. These are particularly appealing for solar installers because they make it easier to install a solar energy system with MLPEs, which can also have the effect of reducing your solar installation costs.

Unboxing Enphase IQ7 Micro Inverters

While you can continue to read about the different technologies, the best way to find out which option works for your needs is to review actual quotes from qualified local installers in your area. Customers who compare quotes on EnergySage can save 20 percent or more on their solar installation simply by evaluating all of their equipment, financing, and installer options.

NOTE: the data in this piece was last updated January and is updated every 6 months. Enphase kicks the snot out of SolarEdge both in quality, customer service and their monitoring system. Enphase has excellent customer service before, during and after installation.

They offer easy to install production AND consumption monitoring with now need for any added devices. You can connect via wifi or a cell kit.Enphase Microinverters are hands down, the best Microinverters on the market. But is a Microinverter the right option for your home? This Enphase review will first point out the advantages of using Enphase Microinverters: reliability, shading, flexibility, safety, and individual panel monitoring.

I explain why I recently complained to Enphase about their attitude towards monitoring warranty, and I share their written response. In the last five years, we have installed about micros on 77 homes. Most of these systems are over four years old, so they are close to halfway through their ten year warranty period. When a string inverter like Fronius or SMA fail, you lose the production of the whole system.

SolarEdge is a fairer comparison. SolarEdge uses both rooftop power electronics optimisers and a central point of failure the SolarEdge Inverter.

How does SolarEdge fair for reliability? See my SolarEdge Stats here. I went to the broader industry to ask for help. I posed the question:. But inverter reliability is only one part of the equation. Enphase microinverters are hands down the best solar inverter solution if your shading is extreme. This is because Enphase microinverters work independently of each other. If you have heavy shading and at some times during the day, just one or two panels are in the sun, those microinverters will produce power.

SolarEdge, in comparison, has to have a minimum of 6 panels in the sun to prevent production loss through voltage blocking. This is explained in-depth in my SolarEdge review. Tigo and Huawei are also good options for shade. They do however require around three or four panels in the sun to get to the minimum operating voltage of the inverter. Read more on my Tigo review and my Huawei inverter Review. However, if shading is minimal, I prefer to use a couple of Tigo optimisers. As I explain later, the fewer Power Electronics on your roof, the better.

Enphase microinverters are often the best solar inverter solution for townhouses and units situations. However Australian solar installation regulations are so strict. Enphase microinverters, however, reduce that risk even further. AC power does not have nearly the same potential for arcing as DC power.

In case of a house fire, Enphase will always be safer.
