I have a 2600w solar array all on separate 100/50 MPPT's. On average it's producing around 800w even if my batteries are from 60-90%. But if i turn on a high load it jumps to 1500w. My question is why doesn't it charge at 1500w even when my battery are at 60%?
What components do you have? Settings? Some screenshots?
I have 4 330ah life-po4 ,smart shunt ,two 12/2000 Multi in parallel, 2 battery Protect 2 Orion 12/30 DC DC charges for alternators, four 545w panels each on own 100/50 mppt, two 160w panels in series on own 100/30 mppt. All my settings are set to life-po4. My mppt setting are 10-14v
But for some reason my PV watts doesn't exceed 8pp-1000 unless I'm using a large load even if the batteries aren't at 100%
Cerbo GX
Always worth triple checking connections.
Is Cerbo DVCC enabled?
If so, do you have a charge current limit set? If so, that's a charge limit, and the GX will not permit charging to exceed that TOTAL value from all connected sources, i.e., if set to 50A, it will prevent all the MPPT and the MP charging from AC-in from sending more than 50A to the battery. Period.
That value does not affect loads. If loads pull battery voltage down, the Cerbo will only restrict charging. The chargers can supply as much as they're able to power the loads.
Thank you i did have it set to 50 . What would you recommend the setting be at?
