Yes, the industrial batteries in the CORE are internally heated and will work in cold temperatures.

It depends on the temperature, sun, etc. The superior insulation in the CORE PRO enables the 10kW-hr system to run for your whole workday in most cases.

Electric heat will typically offer a 30°F temperature rise for 12-24 hours. In extreme applications a fuel-burning heater would allow over a week of runtime.

• Solar adds to runtime. The standard 200W panels can add 5-10% depending on sun. More importantly, they keep the battery topped off when not in use.
• Larger solar arrays are available and can have a significant runtime benefit.

• On a 30A/120VAC outlet, the 10kW-hr battery will take 4-5 hours to charge
• On a 15A/120VAC  outlet, the 10kW-hr battery will take 8-10 hours.

None. Long term storage should be done at 50% state of charge.

• It is much less likely than gasoline to be the cause of a fire.
• The LiFePO4 (lithium iron phosphate) chemistry is considered much safer than many other types of batteries. No combustible gases are released.

No. The battery system is low voltage DC.

With proper use up to 10 years and 2,000 cycles is expected versus ~200-400 for lead acid. The best practice is to avoid using them below 10%.
