Recent analysis by Warwick Johnston at SunWiz shows that the first kWh of battery will always pay back faster than subsequent kWhs, which makes a modular system such as Enphase’s very compelling. One thing everyone seems to overlook is the age of the persons buying solar which also influences decisions on whether the pay back period is viable. Download the first chapter of The Good Solar Guide, authored by SolarQuotes founder Finn Peacock, FREE! For me if the battery can’t repay its purchase price in 3 to 4 years it is of no use, so my price that I would pay is around 3 to $4,000 for a battery that will store enough power for my overnight use which is 6KW. The Powerwalls are AC coupled and will work with most any solar system. I believe they have monopolized the use of this battery in that you can only use specific inverters to use the thing. Contact Us Now I assume 5 kw is minimum. enphase battery vs tesla powerwall 2 ... For more on the Powerwall, read EnergySage’s complete Tesla Powerwall review. Both these inverters are definitely able to talk to the Powerwall. Within the inverter’s world, both SolarEdge and Enphase have a 95% global share of the business. Unfortunately for Enphase, when selling into serves such as Reposit,  power (kW) is more valuable than energy ( kWh) [click here if you think kW and kWh are the same]  So if you want to use these services in the future, Tesla may allow you to make more money. As for the Powerwall: if it is a battery, power in and power out, I would consider it, but I don’t think it is. ... Enphase Ensemble. I current have micro-inverters installed and up to this point was leaning towards their battery solution. I have to use Enphase micro converter (complex roof, shading etc), and an inverter to 3 phase for the heat pump, I assume. Distributed architecture to eliminate a single point of failure, Solar installed on more than 1 million homes worldwide; 8ᵗʰ generation of solar microinverter technology, Manufacturer of solar panels only. That’s a lot of responsibility riding on just one piece of the puzzle.That’s why Enphase invented the distributed architecture for solar and storage.So, what is distributed architecture? In other words bigger the tank the more reserve you have but that also means you must have enough panels to fill up those batteries to cope with demand from the premises they have to power.whilst also been able to charge up those batteries providing you have plenty of sunlight. Where the power restriction of Enphase is s definite disadvantage compared to the grunty Tesla is if you want to sell your power to one of the new breed of ‘grid support’ services such as Reposit Power.
