I own an AC200P. Volts are the flow into the generator. Amps are used by the mppt “at will” to give the volts the optimum wattage. Since the mppt uses amps to control the volts to create watts, a fluctuating response happens.
I bought 10-100w solar panels. The AC200P requirements are 150v/12a. Volts are more detrimental to the generator. The solar panels specifications are 21.6v/5.76a. Using watts law V x A = W, a 6-100w panels in series gives 129.6v/5.76a. 1 more panel takes it just over 150v at 151.6v. How frustrating!!!
Important results:
“Volts are more detrimental than amp to the generator”.
With 6 solar panels at 21.6v/5.76a the volts at the mc4 connectors were actually 132v. 1 more panel is over volts at 153.6v, the Mppt triggers off.
Solution:
Series=combined volts
Parallel=combined amps
Using 10awg (15amp rating) solar wires, 8 solar panels in a 4-series/2-parallel configuration gets 86.4v/11.57a. That fits into the AC200P specifications, with lower “detrimental volts”. Using watts law(VxA=W), you get 86.4x11.57a=978.82 watts. Hold on WHAT!!! Yes its 
fine. The specifications are 150v/12a. My MPPT controller energy loss is about 30%. Because of the length of my 10awg wire length. It runs an average of 666.86w. The bluetti AC200P will only accept 700w no matter how many panels. Its the specifications of 150v/12a thats important.
Configuration:
- 2 sets of 4 in series, connect each series into a double parallel T-branch.
- Connect your 10awg wires leading to the AC200P into the single end of the double branch connectors to the aviation plug.
Secondary solar/ac input:
MC4 connector to D050S to secondary ac plug.
Problem:
The mppt degradation of 34% and the 50v/10a DO50S requirements of (50v/10a) connecting 3-100w panels is way over 50v. Using 2 panels in series with a 34% mppt degradation gives only 134w.
Solution:
AC200P+B230= Storage 4,000w:
Find the highest watt 1 or 2 series panel configuration. I personally use a 400w and get 264w.
My total average watt production of my solar array is 900w.
Continuous:
7.0 cubic freezer, mini fridge, refrigerator and a 50" LCD.
Intermittent:
- 750w water purifier at 4 hrs
- Nuwave oven 30 min.
