The AC500 unit has 2 MPPT inputs, Bluetti states that solar Input is 3,000W Max, VOC 12-150VDC, 15A.
It’s unclear whether the 150VDC limit is per MPPT input so 150V DC1 + 150V DC2 or 150V total combined. @BLUETTI Can you please confirm as I have seen mixed answers?
Each input supports up to 150 volts maximum Open circuit voltage (VOC) so typically you would want to aim a fair bit below that for the Voltage at Maximum Power (VMP). 15A is the maximum per DC input and 3000 watts is the total maximum solar input so that would be 1500 watts per input.
If you had two arrays of 100-120 Volts and 15 - 13 A then you would be at the power station maximum.
The panel I want to add is Jinko 60HL4-V 510 Watt
Max Vmp 37.15
Max Imp 13.73
Voc 44.51
Isc 14.33
So if I connect 3 panels connected in series to DC1 the total will be
1530 Watt
13.73A
133.53V
Then connect another 3 panels in series to DC2 the total will be as above. Total Watt will be 3060 which is fine as far as I understand for the extra wattage.
Also with the 133.53V if we add 10% as a buffer when it gets cold that would be around 147V worst case. It won’t get less than 5°C in the morning where I live.
Yes that sounds optimal. Those panels are a good match with 3 in series and you should have the head room for when it gets cold.
I used an online tool to calculate the voltage swing of your solar array/string. You would need to go below -25C to exceed 150V. Plenty safe enough. The generator has an over/undervoltage limit, but so do the panels as well. A moot point because it is -40C/70C. They list the panel at a temp coefficient of -0.25C which is around the “VERY GOOD” spectrum for mono panels. Cheap ones would be around -0.35C and you get what you pay for. Those panels are very nice.
Thanks for letting me know about that tool!
going to get the panels soon
