Re: Solar charger for 4 6v golf cart batteries LONG TERM?

Renogy (BT model) I am planning the wifi backhaul to the house for monitoring video, thermostat/temp, etc. Maybe even battery state? This will allow us to pre-heat the camper before we arrive in winter. Winter usage is expected if I can get this road done before arctic weather moves in. Just picked up a fitting for the backhoe today. oh yeah- WHAT is MAXIMUM INCLINE/SLOPE of a road for a camper, as a general rule?945Views0likes0CommentsRe: Solar charger for 4 6v golf cart batteries LONG TERM?

I need my generators even with 4-600 watts of solar where I live in the winter..The summer is just the opposite with all the sun.. So you have about 2x my battery capacity (SLA only down to 50%). We've dry camped for a week with less than an hour in the am and an hour in the pm on generator to run A/C, microwave, coffee maker, high amp battery charger, etc. That was for comfort, not dead batteries. They were also new, now about 4yrs old The inverter I have is PROsine 1800 hardwired: https://www.bestconverter.com/PROsine-1800-Sine-Wave-Inverter-Hardwire_p_251.html 1800w with 2900w surge. It can start and run the A/C. Not sure how long, that was an accident when the genny ran out of fuel once. Lol. It's only 1.5w on standby. So low that when we were using it, I just left it turned on. Thanks.847Views0likes0CommentsRe: Solar charger for 4 6v golf cart batteries LONG TERM?

On top of the hill with only a little windbreak on about 30%. Actually considering anchors, just in case. We do get 60-80mph gusts during some storms.848Views0likes0CommentsRe: Solar charger for 4 6v golf cart batteries LONG TERM?

Nearly unobstructed view of sun except for eves, which get cut a little short by the neighboring mountain. Similar to traveling, except no alternator to charge before/after trips. Hoping solar will do that job for us. Thanks.847Views0likes0CommentsRe: Solar charger for 4 6v golf cart batteries LONG TERM?
I tried out that solar calculator. It came back with 530 watts with 55 amp MPPT, 425ah lead acid batteries. Used winter numbers with furnace at 20hrs per day, 0.5hrs microwave usage, etc We have 4x 6v golf cart batteries (Duracell) and 2kw inverter. Batteries are a few years old, always connected to 4 stage charger/AC. Believe they are 215ah/each with 2 pairs in parallel (standard for 12v setup) Likely will be adding a 24/7 camera and internet wifi backhaul link across the top and then down the mountainside to our house. So that will add a little more usage.847Views0likes0Comments
