Mega serials FAQ – OUPES

Why does this device show reverse polarity when plugged into AC power to charge? Does this affect pass-through charging and the UPS?
What are the recommendations for charging/discharging when using the Mega series for the first time?
Can I charge the Mega 3 with a Level 1 electric vehicle charger?
How does the EPS (Emergency Power Supply) function? Does the Mega3 need to be charged to 100% capacity before it automatically shuts off, allowing power to flow directly to the freezer, and then when the main power goes out, the Mega3 takes over?
Can I use the charger from the Mega 3 power station to charge the B2 battery?
Can I stack the products together to save space?
When the Mega series is plugged into the wall for charging, it sometimes displays no current input. What might be the cause?
When my host runs out of power, but the battery pack still has enough power, can I use the battery pack to charge the host?
If I have a B2 extra battery and a Mega 2 hooked up to each other, can I then plug solar panels into both the battery input and the head unit input at the same time?
I have a MEGA3 with two 240 panels. I see the cable coming out of the panel is 14 AWG. Do I have to use 14 AWG wire to extend it another 40 feet? Will 12 AWG give me the maximum flow?

Can this be used sideways or placed at an angle?
Can I charge using a "briefcase" style solar panel with its own charge controller?
When a battery or LiFePO4 battery is installed in a MEGA 3 device, does the system automatically shut down, or should the cable be unplugged?
