Update after Trips and upgrade

So after I realized the misstated capacity of the original single panel discussed earlier, I added 2 120 w panels to the mix. I believe I am now getting around 280 watts. I will say that I...

Thank you SteveJ. I think the 400w hook in this panel might have been an 8 hour extrapolation, so yes. But I sized the rest of the system to support more panels going forward. Challenge is the space...

Added Power sequencing

So I found a 4 channel sequencing relay, which opens circuits in reverse order it closes them. System works nicely. Energize, SCC comes on, 8 seconds later panels connect. Power off Panels...

I found something that should work and follows Boosters thinking, and still lets me power on or off with one switch. The PV and Battery feed are normal relays but I am running the coil feeds thru a...

I became a CPAP user in late 2022, and have found that keeping the inverter in to run it all night is cutting into my boondocking capacity. I have 235 Ampere-Hours of LA batteries. Do not plan to go...
