Panel needed

[shine]

Will discussed the "perfect" solar panel setup for the Bluetti Maxoak (PV input of 500watts, 16-60volts) as being two 250 watt, 50 volt panels connected in series.
I can not find such a panel! Does anyone know where I can get such a panel? Thank you

He's right, but that might not exist as a standard or typical panel...

In order to get CLOSE to 500W, you're almost certainly going to have to over panel the unit.



With the 10A limitation, you need 50V of PV input. That means the panels will have a Vmp at 50V, but a Voc UNDER 60V. Pretty much impossible.

Might be worth a call to Bluetti to clarify 60V is for Voc. If it's for Vmp, you can get there with 3X 36cell (100W) panels. These would have a series Voc of around 68V and a Vmp of around 50-54V.

Add another 3 in series in parallel with the first 3, and you have your 500W peak power with 600W of panels.

Unfortunately, if 60V is the limit for Voc, then you're stuck with less than 400W from 2S2P 100W panels.

60V is Voc
But actual tests are about 67Voc when you get an error code and it stops charging.
The 67Voc cut off has been mentioned here many times.
Bluetti publishes a lot of inaccurate and incomplete specs.

The OP does not state whether he has an EB150 or 240 but they are the same now unless
he has an old EB150 that was only 60Voc

So if he could find 100W panels that are UNDER 22Voc, he could get close to 500W of charging with 3S2P?
