Is a minimum of 100 watts via solar required to charge to charge the B80 ?
The B80 manual states that on page 7 in the context of recharging from a SoC of zero.
However on page 13 it does not mention minimum watt requirement from solar to DC input.
I use a 200 watt solar panel and when marginal sun is available panel output can be below 100.
Will that cause damage if charging from a SoC of say 40 or 50 %?
Whether or not you can charge the B80 depends largely on the open circuit voltage of your solar panel. As long as it is within the B80 range, it will charge.
It won’t, pls don’t worry.
Thanks for the reply.
If it’s not a problem, curious as to why the manual states on page 7 “If charging via solar energy, ensure that your solar system provides an output of more than 100 W”?
Especially in light of the sentence that follows on page 7…“BLUETTI shall not be liable for any equipment damage caused by the violation of the above instructions.”
That seems to contradict you response: " It won’t, pls don’t worry".
The manual writing department explains:
The manual’s statement is in context . It says that if suddenly this battery level drops to 0, it is necessary to restore this battery level by the step 1234.
