You got all the items accounted for there. We use a 20-30 watt mod with a small CC. Happy battery no problem on starts. LPG is a great cold weather start fuel. We have Kohler & Onan that start regularly start at below 0 temps with no issues.
One thing to remember is to check the fluid on the start battery, somehow this gets missed even though the main battery bank gets serviced.

The Cummins Onan 20 kW GGMA (LP, 1,800 rpm, liquid cooled) we're considering also has an optional coolant heater (120vAC, 1,500 watt) that the manual recommends be used any time the coolant gets below 70°F (yikes, talk about a phantom load!) Has anyone used the Onan 20 kW in a cold climate? Was it necessary to use the coolant heater to insure reliable starting? I'm thinking that as long as we keep the starting battery charged with a small PV module, and use the appropriate antifreeze mix, we shouldn't have any problem with winter starting. Thanks again for the benefit of your collective experience! Randy Brooks Brooks Solar, Inc.
