There's not a lot of technical information available about them, don't they have an integrated sinewave DC-to-AC inverter? I could be wrong but I believe they output AC. Assuming a typical installation for their target market, residential, do they require purchase of a separate DC-to-AC inverter?
They're rated at 3.3kW load (AC) to power a house. On Wed, Mar 23, 2016 at 6:48 PM, Bill Prince <[email protected]> wrote: > Only hassle is that they are 450 volts (or in that neighborhood).
