- Charging port (input, 8mm): 14-22V, up to 10A (120W max)
- Power Pole charging port (input): 14-22V, up to 30A (360W max)
- Expansion Module portCovered port under the lid. To be used with Goal Zero expansion modules only
It has 2 charging ports both at 22 volts max....
There 200 watt boulder solar panel they sell has following connector and voltage....
- Anderson Power Pole: 14-22V, up to 14A (200W max)
The battery itself is....
- Cell chemistry: Li-ion NMC
- Pack capacity: 3075Wh (10.95V, 280.8Ah)
At 280 ah, it will take forever (literally) to charge back up with solar. I know when I take my 94ah li-ion 11.1 volt battery all the way down, it takes about 3 days to get it back up to full with just solar (240 watt panel/mppt).
For panels, you going to need the smaller 100/120 watt panels (connected in parallel), those are in the 21 volt range that the yeti input ports are limited too. The bigger 200 watt panels are usually in the 36 volt range. How I read the power port charging port max of 360 watts is probably a max of 3x120 watt (21 volt panels) connected in parallel is the most you can connect.
Its a shame these "giant" lithium batteries are handicap by its limited charging options, they can handle so much more higher charging rates.
