24 volts. 4000 watts. But my question is not specific to a particular voltage or wattage. What I want to know is should MBRF fusing be sized at continuous amps or at surge amps.

Thanks for the help guys. One last question for sizing the fuse going from buss bar to inverter. Inverter is a low freq 4000 wat with a surge capable of 12000 wats. My well pump will pull close to 12000 wats during startup which is very brief, less than a second. I am considering using...

Similar question for the LiFePOWER4 batteries. 24v and 200 Ah. Internal 100amp breaker. Charts say use an 80 amp fuse for the 48” 6awg cable. But maybe a fuse more than 100 amp is more practical so the breaker will trip first? Or is the breaker alone enough protection?

For the BigBatteries which are 24v 170Ah. They came internally fused with a 300amp type-t fuse. They also came with a 48” 6 awg cable. Charts say that the 6 awg cable should be fused at 80 amps. Would it make sense to swap out the internal 300 amp fuse with a smaller 100 amp or 80 amp...

Oh sorry all 6awg cables are 36” and the 1/0 guage cables are 12”.

Sorry about the dashes above. I had it all neat looking with columns using tabs but it got scrunched together when published. I get confused looking at the fuse size charts. They say for 6awg cable to use an 80amp fuse. But the LiFePower4 battery came with 6awg cables and a 100 amp...

I have some rather basic questions about system wire sizing and fuse sizing. Batteries BigBattery———BigBattery———liFePOWER4———IiFePower4 24v 170Ah———24v 170Ah———24v 200Ah————24v 200Ah Built-in—————Built-in———— Built-in——————Built-in 300a Fuse ———300a fuse ——— 100a breaker ———100a breaker...

I should hope so!

If you had purchased your battery from BattleBorn you would not be having these issues. But then again you would have paid a lot more $. I just got my two 24v 170ah batteries from big battery. They were not perfect. One of them is missing a screw on the case. I called to complain. They are...

W What did you buy for $24000? Gold plated battery box?

Good chart but it may be a little optimistic. My well pump runs at 2000W but start surges to 9000W. Actual measured.

I agree. I watched Wills video with interest but realized that these inverters are high frequency with very little surge capability. As I understand it you need to up-size the low frequency inverter so that any surge load is within the continuous rating of the inverter. That negates any...

The Outback has a great reputation. Dont think I can swing the price what with batteries and what-nots. I was really hoping the GS4048 would work but specs say it is just a tad under what I need for the surge

Which inverter specifically?

I have a 240v well and I occasional have extended power outages. I want to hook up a US 120/240 split phase inverter capable of handling a starting surge of 37 amps (9000ish watts) The budget is $2000 ish for the inverter. My preference is 24vdc but can also do 48vdc. Reliability and...
