I&#8217;m looking to put as much solar as I can fit, and enough battery capacity for my typical peak load on the generator panels.<\/p>\n<p>Looking at load, my typical usage on the &#8216;generator&#8217; panel, I&#8217;m running a peak of around 13-14kw, an idle of ~4 (will be higher in the summer).   The other set of non gen panels has larger peaks, but lower averages since it has more non essential things on it.<\/p>\n<p>In terms of amperage and balance, the Gen panel is peaking at ~60 amps on the A-side and 40-45 on the B-Side.    The third graph is the differential, which is less than 20A all the time.  (Neutral current).  That makes a difference in off-grid running because the autotransformer is neutral limited.<\/p>\n<p>4th graph is a typical evening load, which peaked at 13kw on the gen side.  My average power usage each month is around 8MWh, or 96MWh\/yr.  All of this doesn&#8217;t include the 200 amp dedicated TOU service for Tesla charging.<\/p>\n<p>I have narrowed it down to three choices:<\/p>\n<p>(1) An Enphase system, with the smart switch, 3x Encharge-10 10kWh battery systems, and 20kWs of panels.  The Encharge-10 systems can do 3.8kw each, so 3 of them could deliver 11kw from battery, plus the additional 20kw from solar, and of course generator backup from there.<\/p>\n<p>(2) A Tesla system with their panels and  3 Powerwalls.   That would give my 3*13.5=40kWh of storage, and 15 kw of power delivery.  Panels are however DC with a DC inverter.<\/p>\n<p>(3) I roll my own using the Victron Battery+Solar, add Solar, and build batteries.<\/p>\n<p>I am leaning towards #1 primarily because the Tesla setup does not allow generator power to charge the batteries, and doesn&#8217;t really do a mix of generator, battery, and solar.<\/p>\n<p>The Tesla batteries are overall a bit cheaper, as 3 powerwalls would be 23,000 or so with the supporting stuff, while 3 of the Encharge-10s would be about 28k.<\/p>\n<p>Of course I need to figure out how to fit 60 panels on the roof. \ud83d\ude09<\/p>\n<p>Comments and suggestions welcome of course. \ud83d\ude09<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Time for some solar + battery power for the new house.
