Amps needed to charge a battery bank

[Smig52]

I cant seem to find what I am looking for on this GREAT web site.
I would like to set up an emergency PV system to run my refrigerator. I have been researching panels and found what I think is a great deal, but after reading some of the threads here, I think I have found the fly in the ointment.

Panel Specs:
Power (W) 110 Watts
Open Circuit Voltage (V) 141.70 Voc
Short Circuit Current (A) 1.17 Isc
Maximum Power Voltage (V) 110.40 Vmp
Maximum Power Current (A) 0.98 Imp

I have read on a thread that it is the amps that charge the batteries. Am I reading this correctly that this panel only provides 1 amp? Is this an inferior panel because of that or does the high voltage compensate for that. I am planning on getting an MPPT controller. Which I have read on this site that it may increase efficiency.

My ultimate goal is to build a system that will provide electricity for both the refrigerator and a seasonal dehumidifier (summer).

I havent hooked up my KILL-A-WATT meter up to these items yet to determine the exact watt hours that I will need, but I will.

Are these panels decent or a waste of money.
If anyone knows off the top of their head what should be a sufficient, (generic/ballpark estimate), sized system for what I'm looking to do, I would appreciate that as well. I would also like to make it an expandable system for the future.

Thanks for you advice.

They are made for grid tied systems. You can use them on a battery system if you use a MPPt controller. They will down convert voltage and up convert amperage. So at the output of the controller the output would be around 12 volts @ 9 amps.

However not all MPPT controllers can convert that high of a voltage down to 12 volt system. But who says you have to use 12 volts. It is the worse choice you could make. 24 and 48 volt is a much better choice.

It's best to convert all measurements to watts. Look at the yellow energy tag on your fridge, it likely says 450KWh a year to run. that works out to 1.3KWh daily.

So, in your 4 or 5 hours of good solar sun, you need to harvest enough to run and recharge the battery bank 1.3KWh. roughly speaking, you need to harvest 3 KWH over a 4 hour period. That needs about 750W of panels.

Then a couple batteries, charge controller and an inverter.

or a small gasoline genset.

Thank you for the fast response

Thanks guys. Love this site.
