You can now expand DJI’s Power 1000 solar generator that I reviewed with up to five of these new $1,169 2kWh Power Expansion Battery 2000 units daisy-chained together over DJI’s proprietary SDC port, for a maximum capacity of 11kWh. Add solar and you can produce a steady 2400W of AC output indefinitely, or at least until you master a rosetta pattern in your latte art.
