Hey Folks,
Def a newbie/beginner in the Solar World . . .
Starting with a small Bluetti EB70 power station thought it would be pretty straight forward, but two 230W used panels I bought were too high voltage, pic attached.
So I'm currently borrowing a smaller panel (120W - but inputs seem capped at 90W) from a neighbour, but with my fridge running, a Dometic CDF-36 (12-24V 60W), if we have a few days of partial sun it drains the battery.
I figured I'll move the fridge to a cooler place in the house and make a cover for it to improve insulation, but also a bigger panel will charge more on those cloudier days and guarantee full charge on a sunny day with the fridge running.
My questions are can I run one of those bigger panels using an external solar charge controller capable of higher voltage, or I've seen 'buck converters' mentioned but not sure what those are?
Or do I have to buy a newer 12-24V panel closer to 200W? There is a used 29V panel going on Marketplace but that's just outside the 12-28V OCV range for the EB70? I also wondered about connecting the two diff panels I have in parallel (one of the 230W used ones and 120W neighbours), if the voltage will be restricted to the lower of the two (my neighbours one), thus will work with the EB70?
Look forward to hearing your responses folks and becoming a part of the Community.
Ta,
