The build: 840 watts on roof, 40 amp epever scc, 206 Ah sok, unheated trailer unless I'm in it, winter Canada battery still never gets below about 12.8 volts.
Outside temp = inside unheated, only a question of how long it takes.
Typical winter outside in the -20 c + windchill. Let's just call it -40.
Pics added.
Insulation on floor, heat pad, aluminum heat sink.
The excess layers/ buildup from floor is to cover the heat pad wire loop from room temp.
Finally, the couple questions.
1. The +- 4" on wire end has no 'heat.
Anyone know, where is the 'built in' thermostat?
Does that insulation layer cause it to 'see' heat n shut off?
I'm less concerned about battery too warm, or even above 0 charging.
Should I trim the insulation back on the wire end?
2. I trust the SOK bms to guard my battery.
Does the temp sensor on MT50 control charging, or simply give me info?
Thinking, cut back insulation on the end n get sensor buried against battery.
Snap disc thermo will be added to pad circuit later.
Thoughts?
Offer advice, not more sh#t to buy.
Thanks.
