Grid Abandonment by state: ( and septic, water too ) https://www.primalsurvivor.net/living-off-grid-legal/

You have to find out what the Grid Abandoment rules are for your area/PowCo You might get your house red-tagged by a building inspector if the PowCo reports it. The PowCo usually enters into a "arrangement" with the goverment to insure they will have enough customers to make running cables...

I'm not sure how to interpret that statement. My inverters produce 240VAC split phase (120V per leg) Hooking up a 12-30V LED is not going to end well. Do you have an example ?

I'd say a big fat no, if you are going to try to have any property insurance. a) LV lighting might be efficient at the bulb level, but the cable runs to the bulbs will need to be beefy 10 or 12 ga wire. b) Inspector is going to want to see UL labels for the sockets, bulbs and DC switches c)...

Overpaneling generally means higher wattage, not higher voltage, which is deadly to charge controllers Better controllers have output limiting and thermal foldback to keep the controller healthy when overpaneled.

Thats 2 tenths of a volt for margin. I guess it's ok. But there's something about holding/charging Li batteries at a high voltage for a long time. I think 5 minutes is enough, but they are your batteries and you have the manual.

I'm partial to the Schneider Electric solar gear The XW6048 inverter that I use, accepts 240VAC from either of my 2, 240V generators, and can use the AC power to become a large battery charger (over 100a @ 48V) It also has a Generator Support mode, and if you approach the programmed limits of...

So, if you are "creating" a Solid State Relay (SSR) they have nearly the same style of parts inside. And they also have engineering data sheets that describe "snubbing" circuits to damp out the inductive kickback when turning off and on. While it's DC, it can also "kick"...

I am concerned that your lead acid charger does not have the right voltage presets for your LFP batteries. What does your battery documentation say their max charge voltage is ?

3kw is a lot to ask from a 12v system. Have you considered 24 or 48v

If you want to replace a bad Bypass diode in a PV panels' J-Box, you can use an "Active Diode" which is a FET switch purpose made for solar. Several companies make them , and they dissipate less heat than a Schottky diode...

Most charge controllers provide the blocking diode function, but if you want to waste some not insignificant amount of power forward biasing a diode all day, be my guest. If you want to replace a bad Bypass diode in a PV panels' J-Box, you can use an "Active Diode" which is a FET switch purpose...

Better calculate your power consumption for a 24 hour period. Then you need batteries to run that long. When we had fires nearby, the smoke was so thick, that the sun was not visible at noon. I had no solar harvest for 2 days. The light in my generator shed, was a 10W LED, way brighter than...

Their supplied opener inverter is likely mod-sine, which will "work" in a pinch, at the cost of overheating the motor because it's not pure sinewave
