How should you choose a heavy-duty power station?

Start by identifying the largest appliance you plan to operate and its starting power requirement. Then estimate how much stored energy you need between recharging sessions. Next, think about where the unit will live and how often it has to move, since weight adds up quickly at this size.

If you may want more storage later, the DELTA 2 Max and DELTA 3 Max Plus can add batteries. The Elite 400, Elite 300 and Elite 200 V2 cannot add batteries. Finally, compare any solar panels you plan to use against the voltage and current limits of the unit you choose.
