FranklinWH Energy Storage FAQs

What is the installed cost of a FranklinWH aPower battery system?

A single FranklinWH aPower (13.6 kWh LFP battery) with the aGate intelligent controller typically costs between $11,500 and $14,000 fully installed. After the 30% Federal Tax Credit, the net out-of-pocket cost is approximately $8,050 to $9,800.

How does FranklinWH compare to the Tesla Powerwall 3?

FranklinWH features 13.6 kWh usable LFP chemistry, built-in generator integration, and intelligent circuit-level smart controls via aGate. The Tesla Powerwall 3 offers 13.5 kWh with higher continuous power (11.5 kW vs 5.0 kW) and an integrated solar hybrid inverter. Both qualify for the 30% Federal ITC.

How long does it take for a FranklinWH battery to pay for itself under NEM 3.0?

Under California NEM 3.0 and utility Time-of-Use (TOU) rates with peak evening electricity costs of $0.50 to $0.62 per kWh, a FranklinWH battery system achieves payback in approximately 4.8 to 6.5 years through solar self-consumption and peak rate arbitrage.
