Shunt options

andy300z

Hello
I am in the process of purchasing a trimetric 2025 and i will like to know what type of shunt i should get.
I am planning to run my small office with a 12v samlex inverter1500 watts.
My office only uses 400 watts and 1000 watts when i run the laser printer.
Should i get the 100amp or 500 amp shunt.

Thanks

Re: Shunt options

1500w / 12v = 125a which is too high for a 100a shunt. So get the 500.
