Need advice. Will pay if necessary.

I just bought a Bluetti AC200 and 4 Dokio 300w panels and just want to know what I need to do to make things work right without buying the wrong connectors and wires. I'm not even sure if I can use these panels with my power station. Do stations like this down-regulate excess amperage and use remainder? If I have 4 panels in series generating 80V in total and the 700W max the solar input will accept, does that not equal 8.75 amps so that it would come in under the 12A max the power station accepts? I don't know how to know and would be willing to pay for some qualified help.

So, with a max spec of 700w, I think only 2 of your panels are able to be used with it. (600w)

I'm not sure if they will work.

I see the input specs for solar panelsto the Bluetti is 35 volts. Two of your panels in series will make 35.5 volts, so that's close to the lower limit. Running a single panel or two in series will provide up to 18 amps in both cases which exceeds the 12 amp limit. I don't know if you can limit panel production to 12 amps, and you are likely to exceed 12 amps for a while each sunny day. If it were limited to 12 amps, that would give you about 436 watts between both panels.

I think Bluetti designed their system this way to get you to purchase their solar panels, but allows you to buy other manufacturers, but just makes it so hard to do it, its not that you can't but why go though all that effort? Seems like the government: submit your idea in triplicate on the correct form, and we'll get back to you.

If you're going to put panels in series for this Bluetti, amperage output of a single panel needs to be less than 12 amps. From when I've looked, you can get a 100 watt to 175 watt panel which usually both put out 18 volts and 6 amps for 100 watts and around 10 amps for the 175 watts and string three of these in series. Of course these smaller panels are pricey, often more pricey than 300 watt panels.


================


If you have 1200 watts of panels, you can pick up an Solar Charge Converter, add it to up to 4 golf cart batteries, and then you have yourself a little over 5000 watt hours of power.

If you set the batteries up in 12 volts, a 50 amp Charge controller will provide a max of around 700 watts of charging, and wire four batteries in series to get 24 volts, your charge controller will get you around 1400 watts of charging, which is slightly more than your panels provide.

A PWM Charge controller: $50
A Decent UL458 approved 1000 watt inverter $458
