Anyone here ever heard of Sunforce Inverters
I had posted a while back about a large solar install. Unfortunately, dollars and complexity killed that dream off for now. I am sure technology will catch up and permit what I had originally thought ...

Have you thought out what happens when you draw 2000WATTS from an INVERTER connected to your battery setup...
The INVERTER will draw somewhere around 12.3VDC@162AMPS from your battery bank. The big question I would think is how long will my battery bank produce 12.3VDC with that load on them...
The specs says it will produce 12VDC@20AMPS load for 447 minutes (7.5HRS) for two GC2 batteries connected in series. Having two groups of these batteries will increase that to 894 minutes (15HRS). This is ONLY for 20AMPS drain from your batteries. You need to find out what happens when you pull 175AMPS of DC current from your battery bank before your Inverter kicks off-line when the DC voltage drops below 11VDC.
The only experience I have had first hand was pulling 1500WATTS from a single 105AH 12VDC battery and it only lasted about 12 minutes. This was with a rental car with the motor running. It killed the alternator as well...
I'm thinking if you want to pull a total 2000WATTS continuously you will need alot more batteries in your setup... If you are going to use your 2000WATT Inverter for maybe some 300-400WATT combined loads it will be a different story.
Might want to talk with the guys that live 24/7 off the power grids in their motorhomes and see how big their battery banks are to survive on...
Large WATTAGE Inverters are very very battery hungry.
