Short answer: The Enphase IQ Battery 5P is the most flexible and installer-supported system. The Franklin Electric aPower 2 offers the best power-to-price ratio. Tesla Powerwall 3 remains the most polished system but uses NMC chemistry. The best system depends on your inverter, installer availability, and whether you prioritize power or longevity.
