Component Sizing for 600AH Lithium
I'm getting the components for a 600 amp hour LiFePO4 parallel battery bank install with a 12V 4000 Watt Giandel inverter. I need some help sizing other components. Specifically, how large of a shunt will I need for my battery monitor? Also, how large of a catastrophic fuse will I need? It may help to know that my inverter will have a 4000 watt nominal and a 8000 watt surge capacity.
My install will be done in 2 phases. Phase 1 will be the setup of a battery bank and inverter system. If you want to critique any other sizing as it related to the battery bank, so far I am planning to use:
- 3 x 200AH LiFePO4 batteries (Ampere time)
- 1 4000W Pure Sine Inverter (Giandel)
- 1 TRC 50 Amp Automatic Transfer Switch
- 1 Progressive Dynamics 50 Amp Lithium Battery Charger
- 1 BONATECH 600A 12V-48V High Current Battery Switch
- 1 bayite DC 6.5-100V 0-100A LCD Display Digital Current Voltage Power Energy Meter
- 1 shunt (will I need a 500 amp or will a smaller one work?)
- 1 catastrophic fuse (will 500 amp work here or should I go higher given the inverter and battery bank?)

- 4 AWG Gauge Wire
