Re: Inverter repair
I agree with Bill. Here below ..... is a copy of my OzInverter build manual from the tech section. Its a straight to the point contribution by a well respected, good and clever engineer in Australia.…1 · -
Re: Absorb Time for LiFePO4
When I first started reading here (a long time ago, and I had just installed a GT Inverter system in my home--Still no battery/inverter system, just a backup eu2000i genset), I was reading about batt…1 · -
Re: Question about battery/cable lugs and battery connections.
You are referring to maybe a 1/4" of area for the current to pass through. Cables are important because several inches are involved. Consider the safety fuse which really amounts to a much smal…1 · -
Re: Selecting panels
It's not quite as simple as it will/won't work with mppt. An mppt cc needs some overhead pv voltage to buck down to charging voltage. I've seen suggested minimums of 20-30%. The actual overhead will …2 · -
Re: voltage control
Don't forget the heat sinks ! Half the purpose of turbine protection is Over Voltage, the other thing is Overspeed. You need a bank of load resistors to switch in to load the turbine down to prevent…1 · -
Re: Fangspun mppt
you will need to have minimum of 2 panels in series to properly charge a 24 V battery bank. The CC will generate a lot of heat etc. if 3 in series is used for 24V bank. Best to go for a name brand CC…1 · -
Re: Fangspun mppt
One other generic set of questions... You need to match the Vmp-array with the Vpanel input rating and Vbatt output of the solar charge controller... If you have a 12 volt battery bank, then any reas…1 · -
Re: Fangspun mppt
I can't say that I would recommend the brand. While I have no experience I can say that Fangpusun seems to copy many of the established brand solar charge controllers, at least on the surface. Intern…2 · -
Re: String size advisable?
In strings of 2 assuming array output of ~2000w, that would be something like 2000 ÷ ~70vmp = 28ish amps per array into each CC. That gets bucked to ~80a into a 24v bank. The array vmp will vary a bi…1 · -
Re: Using 12volts off a 24volt system
There are converters made for RV/busses/military trucks/etc. that connect to the 24 and 12 volt busses, and will charge/discharge the two sets of batteries to be equal state of charge (24 volt chassi…1 ·
