Hey all,
I'm setting up a 12v system to run a few circuits in my home (Internet Router, WiFi, desktop computer). However, I also want to run my refrigerator and separate freezer off of it. I've already hooked a kill-a-watt up to both the fridge and freezer and let it run for several days. The normal draw of each is only around 200 watts (when running). However, the momentary surge hits up around 1000 watts for each.
So I'm thinking... There is the possibility that both the fridge and the freezer can kick on at the same exact time. This draw, plus the existing 200 watts of electronics, can put things momentarily up around 2200 - 2500 watts.
Most Inverters/Chargers or AIO units at the 1000W range spec around a 10-15 Amp AC input breaker.
Question: Is it OK to size the inverter, cabling, and fuses to the normal ~600 watt range? This is assuming that any fuses and/or AC circuit breakers spec's at that range can handle a momentary surge above that rating? IE: A 10A AC Circuit Breaker can handle a momentary surge of 12-15 Amps. I'm assuming the same can be said for the DC side...
Thanks,
Jeff
