I received my 200Max yesterday and configured the 200Max with my old 200P. My plan was to use the 500-watt charging block to charge my 200P from my 200Max. The solar runs into the 200Max. It works great. One thing I did not realize, because I had not used the power block before, was that when the 200P gets to 100% charged, the charger shuts down. That way the whole thing is automatic.
The only problem I have is that my 1,340 watts of solar that used to put in the 700-watt maximum in the 200P in the summer, is now on a relatively cloudy day, only pushing 350 watts into the 200Max. Anyway, I’m happy with both units. When I get my D050s I will see if it is more efficient than the 500-watt charging block.

Curious, when did you order your 200MAX? Glad u got it. I really wanted to order it at this last sale but not committing funds for new bluetti products when prior orders pd for but not yet fullfilled/shipped.
Roxie, my order was dated Sept 17th.

@Pistulka99 Hi there，
The charging by solar panels is automatic.
There are some factors that affect the rate of charging using solar panels.
- The amount of sunlight
- Conversion rate of solar panels
- The angle you place the solar panel
- The length of the solar cable
If the solar panel conversion rate is 70%, only 70W of 100W solar panels are available.
If the sun’s light is too weak, the conversion will also fall.
If you charge the unit on a cloudy day, the power would be very weak.
Thank You,
I was not questioning why I was only getting 350 watts. I was just stating it as a fact. I knew that with shorter days in fall and winter, and less direct sunshine, the panels were going to produce less power. I just hope the next power outage comes on a sunny day.

Do you have 4 x 335W panels in a 2s2p setup? That would give a Voc around 90V and maybe 18A of max current. Pretty idea for a 700-900w input. There’s not too much you can do about the sun on a cloudy winter day, besides perhaps adding more panels.
I have 4 x 210W and 5 X 100W. The 210s are in series and the 100s are in series wired in parallel into the house. Like I said I could easily max out the 200P at 700W. My problem is that was in the summer. I was waiting for the 200MAX to arrive, and I have not gotten around to taking the panels apart and facing them in the correct direction. When do that, I will most likely come close to the 900W on the 200MAX on a good day.
