How about one of these all-in-one inverters? https://www.mppsolar.com/v3/hv6048wp/
There is a thread about it here: https://diysolarforum.com/threads/new-all-in-one-mpp-lvx6048wp-ul-certified.23505/
Looks good. 20kWh of storage should carry 350w of loads for 3 days during cloudy weather. I would add auto starting generator and chargeverter. The only thing I don't like are those batteries not reporting SOC for telemetry.
Inspired by that design here are my literally back of envelope doodles. The idea to use cheap pipe or rebar driven into ground vertically as support with custom made brackets which can be made for a $1 each.
I wonder what's the PoE voltage range starlink radio will accept? Could be possible to run direct from LFP battery without dc-dc for better efficiency.
You should get 600V DC rated MOVs for PV- to ground and whatever is your PV voltage + 100V for PV+ to ground and PV+ to PV-. Would need 3 per side or 6 total. I prefer MOVs with built-in gas discharge tube but GMOV only goes up to 415VDC which is not enough.
Got it talking with BMSTest software. So It looks like you can't edit voltage setpoints with these BMS boards. Kinda lame but understandable since these batteries supposed to be safe from user tampering.
So it only glows when neutral is connected (blue). Seems like capacitive coupling from neutral to concrete ceiling. Set your multimeter to AC voltage and measure from LED fixture metal case to neutral. Scrape off a bit of paint to make contact. Start with highest voltage setting and work your...
No, induced earth potential from nearby lightning strike will induce high voltage between DC and AC side of your inverter possibly damaging it. All ground rods in your system have to be bonded together via #6 bare copper wire (except those ground rods used purely for air terminal lightning rods...
