I havent finished my system yet: I'm testing with a lead acid battery that is being abused but will be upgrading to a LifePO4 battery with built in BMS. I am running an 80W thermostatically controlled fan and about 5A of automatic lighting. On a hot summer day the fan will run down the...

Makes sense. I assume that the output coil controls the ac to the psu transformer and that the output of that is connected in parallel with the battery output to load, but downstream from the blocking diode. So that when the battery dies and the relay kicks in with the power, the new supply of...

The renogy rover mppt controller has a load output that puts out 12v as long as the battery has enough juice in it and can be programmed to turn off if it drops below a threshold. That's what I currently have everything hooked up to, so would probably go: Battery +| |- | |...

Relatively new to this. Installed a 400W solar system on my shed to power lights and a fan for the summer. Using the renogy rover MPPT controller with a 12V lead acid battery to manage everything. No inverter. Battery is somewhat undersized but (a) probably wouldn't solve the issue if I got a...
