Hi Kevin, I have seen the X240's trip off like this when theyare over loaded. When this was happening to us the slave inverters had blown AC boards and some times Control and FET boards too. We had a hard time diagnosing this as their green lights were on. Using a clamp on amp meter on each inverter's AC IN conductor while charging with the gen set allowed us to compare their charging currents to each other. Typically the ones with blown AC boards output would be close to zero amps. So the X240's were doing double duty and they will smoke too if the inverters aren't delta with.

Quad stack VFX3648. Last night gen start was triggered by low voltage - a normal system operation. Approx 1h into charge, they lost 1/2 the circuits in house - L2 de-energized. Caretaker went to check power system and noticed the X240 breakers tripped. Tried to reset but it tripped out right away. So he left it as is and called me in the morning. Here's what I've been able to determine today: - The x240 is installed to bridge L1 & L2 on the load side. - with master inverter on, 3 slaves off, both L1 and L2 energized so suggests x240 is working. - within 10 seconds of generator on and charging, x240 breaker trips (and makes L2 go dark). - loads are minor, ~1,000 w of misc lights and such, isn't all loaded up on one leg. Appreciate any thoughts to remedy. I'm not as familiar with this config as others.
