After 100's of thousands of inverters having been shipped in the last
many years
and thousands of inverters broken and shorting the battery terminals,
there has
never been (to our knowledge) one breaker that has not tripped.
The Midnite site lists the AIC rating of all our breakers I believe
Hey Bob;
Can you share that AIC vs Voltage chart?

Those 250 amp and 175 amp breakers we have used for many many years now
have an AIC of 50,000 amps at 125 volts and if you look at the curve, at
48 volts
they are around 100,000 amps. I think that this information is on the label
of the breaker.

For grid frequency regulation on a larger project you might want to look
at Beacon Power flywheels. They produce a large carbon fiber flywheel
that can put out as much as 250 kW for short periods of time. It isn't a
long term storage solution - more like a huge capacitor. They list cloud

I just went through this with SMA tech support on the Sunny
Islands. The breakers built in to the SIs have a 10,000 AIC
rating. The battery bank we are using, one string of Concord PVX
3050 T, 305 AH clearly won't surge to 10,000 Amps. We decided that a
series fuse isn't necessary on the bat
