Wattage as in the the list rate of the panels or as in ohms law . Volts x amps= watts. So in this case the total watts I have available appears to be 408 watts. As figured by the amperage draw. Just as a note, the reason I was using the before and after was to give as much clarity as possible...

Fully depleted was a resting voltage on the batteries of 22 volts . I’ve yet to figure out where it’s all going. I do have a chest freezer and a large twin door fridge. I fear that’s where the draw is.

It’s a 24 volt system . Input voltage in to the controller is roughly 56 volts from the panel. Amperage from panel to controller is 8.2-8.6. The battery bank Is 2-300 ah 8d battery’s that I have wired in series. I have 4 panels 230w . They are set up as 2 parallel and series banks. To get the...

Mattb4 The panels are putting out at best 17 amps real world, at 24volts. Everybody says it should be higher but that’s what they are putting out. And I have tested each panel . There all contributing . Even by your numbers that 11 hours would at best be broken into 2 days . That’s rough. Need...

Just doing some math. So I have 2 8d lead acid batteries. I believe they are supposed to put out 600ah in total. This give me 4 hours of run time. So that means I’m burning up 150ah a hour? I have 4-230 watt panels at best I’ve only been able to pull 17 amps out of them. But usually closer to...

I’ll send a new screen shot. After the last picture I put them In series . So it 2 banks of paralleled panels put in to series . A total of 4 panels

I wired them in series. Gives me less amps coming in and more going out. But still not any more the 10 or 12. Amps. Would this give me a longer 24 volt charging window because the panels are putting out higher voltage? So instead of 3 hours a day I’m getting charging occurring it’s would now be...

Hey thank you I appreciate it

These panels are poly. I disassembled a solar farm that was up dating so I have access to 150 or so used panels. I’m currently wired for 24 volt. The panels max output is 32 volts. panel max amp is rated for 20, once again I get that it wasn’t going to be 20, just was expecting more then 4 amps...

Right now with direct sun on the panels I’m getting 12 amps on the input, and the same for the battery.

Oh roger, got your you were talking about a range. Sorry had confused the heck out of me. Just feeling a little lack luster in the charging capacity for my battery bank. If I’m truly only going to get at best 20 amps total from 4 panels. The math to charge my existing battery bank would be 90...

20 amps converts to 45?

I wired the panels in a set of poly j boxes. I tied the panels together in sets of 2. Wired in parallel, then used a wire large enough to carry the combined rated amperage to the controller. I can test either set of 2 for power but not each panel separately . It ( the controller) shows both pv...

Four 230 watt panels only produce 460 watts? What am I missing. I was figuring in the 900 watt ball park?

I have a OOYCYOO charge controller supposed to be rated for 100 amp. Little back around, I have 4- 230 watt panels at 24 volt. I’m using them through the charge controller to charge 2- 8d deep cycle lead acid battery’s. While the systems being used or while it’s in stand by. The max amperage...
