Hi,
I have an EcoFlow Delta pro with 2 extra batteries in my travel trailer. Currently, I run the EcoFlow 400-watt panels x 4 in a 2S2P configuration.
- EcoFlow Delta Pro - MPPT 1600W Max, 11-150V, 15A Max
- EcoFlow 400-watt panel - Open Circuit Voltage 48V (Vmp 41V), Short Circuit Current 11A (Imp 9.8A)
I would like to supplement these with ridged roof panels on the travel trailer. The roof panels will be:
-RICH SOLAR 200 Watt 12 Volt 9BB Cell Monocrystalline Solar Panel -
2 of these in series is roughly equal to one of the Ecoflow Panels.
I was originally thinking I would get 4 of these and combine them in a 2S3P configuration (4*200watt panels in series in parallel with 2*400watt and 2*400watt). I would put these together in a combiner box before going into the DP.
However, I am getting worried about the possible 30-40AMPS that could be going into the DP when it can only take 15AMPS. Where will that excess go? Heat Smoke? The XT60i to MC4 connector that the DP comes with is definately not gauged enough to handle that amount of current.
So then I thought I would add 2 more 200watt panels to the roof, ditch one of the 400watt external panels and run a 3S2P with 3 of the 400-watt panels in series. This seems ok, but will I run the risk of overvolting the DP with the 200-watt panels when the temps drop? 24.3 * 6 = 145.8
Which of these configurations seems better? I appreciate any help on this!
