How should I go about connecting five 40-watt solar panels to charge AC200MAX?
Hi @bluetti_bcalertpalgmailcom
Welcome back!
To better help you, it will be great when you can share the specs of your 40W Panels and the way you want to play them. Interesting values would be the VOC and current.
greetings

Thank you for your reply.
I hope this will help. Power Rating: Maximum rating 40 Watts (under ideal conditions)
Current: 2.3 Amps @ 17.1V
For additional info, please go to: 40 Watt, 12-Volt Crystalline Solar Panel - Sunforce Products
Using five 40W rigid panels to charge the AC200MAX is not an ideal choice, but you can connect five in series using MC4 connectors to the AC200MAX. Compared to the PV input parameters of the AC200M, you will find that the charging efficiency of these panels will be very slow.
Don’t use the solar charge controller.
To put them in series, as Bluetti-Admin advises you, you will need SAE - MC4 adapter cables like these to connect your panels in serial directly to the bluetti solar input.
