Hey guys!
First off, I love you guys. I appreciate all the thoughtfulness and help that you guys give to everyone. Thank you all for your time.
I have a 1990 Terry 30 foot camper. All original electronics. Fuse/distribution box, 120v plugs, 12v lights, shore power extension cord, and there’s a converter that charges the 12v battery when plugged into shore power. It is plugged into its own 120v plug and when it gets power, it runs the 12v system, and charges the battery. (Right?)
When I bought the camper, someone wired in an inverter, direct to the battery and put it inside the trailer. When I got the trailer parked on my property, I added three 100 W 12 V solar panels, and 2x 6 V golf cart batteries and a PWM charger. It’s a Morningstar PS30 older gen, this one: https://cdn.shopify.com/s/files/1/1...15-Straight-Main-Fr_3_grande.jpg?v=1523042233 Works fine.
I recently built a 280ah lifepo4 battery with a daily BMS. Picture attached. And I want to replace my golf cart batteries with it.
Q#1 can I use my existing pwm charge controller or should I get a mppt charge controller for my new lifepo4 battery? My panels are old and I’d like to upgrade soon, so I assume getting a mppt would be a good idea.
Q#2 main question; Can I hook up my inverter to my existing power system such that my existing 120v plugs will work off my inverter? (Instead of just the 2 plugs on the inverter itself)
Q#3 If I CAN hook my inverter to my existing 120v plugs, what do I do so that the plug that my 12v charger/converter is plugged into, doesn’t start up and attempt to charge the 12v batteries that it would be being powered from?
If shore power is plugged in, or my generator is running, the battery would be charging via the 120 to 12v converter. But if shore power/generator is not plugged in, and my 120v plugs would be battery powered through the inverter, what can I do to stop the 120 to 12v converter/charge from attempting to essentially charge the battery from itself?
Is there a work around? Would I need to rewire my distribution box / power system with newer components?
As always, thank you all for any advice or ideas.
