Wrenches, Here's one of those threads to save if you expect to do large multi-inverter battery-based systems. This is a thread from last August, with recent updates. Bottom Line: in a large system with Sunny Islands, use a 1,000A/50mV shunt, not a 1000A/100mV shunt.

[RE-wrenches] Shunt question

2012-07-31 Thread Allan Sindelar
Wrenches, What are you using when you need a shunt larger than the standard 500A/50mV? The application: four Sunny Islands and a Radian in a large grid-tie with backup system. Total current flow through B- is rated 850A (using 125A SI DC breakers) or 1,050A
