If you have load amps on your battery terminals (except for really large loads, like an inverter), you're wiring it wrong.
nope, if your not using the timed light control for eve lighting you have it wired wrong. :W
Darn, the factory has the furnace running off the battery, not from the solar controller. But I only use the furnace at night. I can't figure out what to do! I think my brain is wired wrong.
They wired it wrong. A Suburban NT-20SEQ draws less than 3 amps. Even most of the cheap Chinese controllers can handle 10+ amps. My Morningstar can handle 30A of load, which is more than enough to cover everything I could turn on, all at once - furnace, water pump, all lights, fridge, TV, more. Like I said, no need for an external shunt.
But, since you only run the furnace at night, it doesn't have any affect on the battery current the controller is reporting when the sun is up, so still no need for an external shunt.
