Help with custom Morningstar Tristar PWM setup

Ok, reading back it seems there is usually a small load on the inverter while the battery voltage rises under solar, then you yank that small load and the inverter alarms off. ??

Groucho Marx, playing doctor on his TV show, had a line with his patient, "Does it hurt when you do 'That?' " "Yes" said the patient.

"Then don't do 'That!' " said Groucho.

IAW leave that small load on instead of yanking it, and you won't get any spikes that shut down the inverter. :)
