Generator shut down error
I have an off grid system with Schneider gear, solar panels, and a Baldor generator (before Baldor was bought by Generac). In the winter the power shed is around -5 to 0 degrees Celsius. Heat to generator comes from my battery room which is heated. All within one power shed. Winters where I am are -20 degrees Celsius.
When the batteries reach my preset limit, the generator auto starts. My problem is the generator is shutting down within 1 minute from an error: Gen L1 & Gen L3. I have watched the generator on start up and what happens is the L1, L2 are jumping around +-120V. The L3 around 240V. Then the load hits and then all within 5 seconds they rise up to around 180V on L1, L2 and 340V on L3. The engine then shuts down from a load unbalance. It doesn't happen every time, but I think must be a problem when the house has a bigger draw at same time.
I think the problem is my generator has not had time to warm up. It has been serviced and looked over by a good generator tech. He was the one who mentioned I should try plugging it in. Problem is the block heater uses way too much power.
The generator has settings that should delay the load and let it warm up, but the system control panel seems to override it and power starts being drawn in under 30 seconds.
Is there a setting in the system control panel that will allow my generator to run for 3-5 minutes first to let it get up to operating temperature?
It is a big problem because the generator kicks to manual off from this error and won't auto start next time the batteries drop down. Essentialy making it that I can't go away for extended days in winter.
