Enphase Ensemble Solar Back-up

One of the more frustrating facts about standard grid-tied solar power systems is that they do not provide back-up power during power outages. While there are some solutions out there that will allow you to use your solar as back-up power, none of them compare to the new Enphase Ensemble technology that will be available very soon.

Most existing solar back-up systems are small and can only provide enough power for some lights and your refrigerator. A solar back-up system large enough to run large appliances like an air conditioner or hot water heater is possible with current technology but it means filling your garage with batteries and inverter equipment. This will be very expensive and the installation is complicated. If you are attempting the Holy Grail of solar back-up, the whole house back-up system, you have to source a transfer switch from the generator industry that is not programmable and may not be suited for all the sources you want to incorporate.

But Enphase has the solution with their new Ensemble back-up system.

One key component of the Enphase Ensemble back-up system is the Enphase Encharge Storage System. This is an AC Coupled, Lithium Iron Phosphate energy storage unit with integrated Enphase IQ8 Multimode microinverters. The Encharge 3 has 3.4 kwh of usable storage and the Encharge 10 has 10.1 kwh of usage storage. For more storage, multiple Encharge systems can be connected to create a system large enough to provide the whole house back-up system. The incorporated IQ8 microinverters have new processors that can react in 20 nanoseconds to loads coming online and offline so that they maintain an independently stable AC grid throughout the duration of a power outage. Having the battery storage and inverter incorporated into a single unit simplifies installation making it very possible for a do-it-yourself solar installer. Also, these sleek units can be hung on a wall and are even rated NEMA 3R for outdoor installations.

Another important part of the Ensemble system is the Empower Smart Switch which has multiple configuration options and even includes a place to add an additional back-up source like a diesel generator which will make the perfect system for the serious doomsday prepper. The Empower Smart Switch manages all the power from the Encharge Storage System, IQ microinverters, grid and generator. If the grid goes down, it seamlessly transfers your house loads to the storage system and IQ microinverters. When grid power is restored, the system transitions back to normal grid-tied operation. 

Not only will this system provide back-up power during outages, it can save you extra money when the grid is on by managing power to optimize time-of-use electric rates. It will store excess solar power during off-peak times when the electric rates are low and provide power to cover your loads during peak times when the electric rates are high. 

Finally, the whole system can be controlled and monitored from the user-friendly Enphase Enlighten app on any smart phone or mobile device. It doesn’t get any easier than that.      

The new Ensemble technology is compatible with any Enphase IQ6 or IQ7 microinverters so customers who already have solar installed with these microinverters can retrofit their systems with the Ensemble back-up components. Customers installing the solar and back-up system together would install the Enphase IQ7 microinverters just as they would for solar without back-up and then add the Ensemble components.
