Same inverter in both. The 200 covers the standby load: router, modem, chargers. Pick the 400 if the fridge is on the list. The 400 adds a second panel for a bigger daytime load.

The 400 W kit's extra $200 buys a second 200 W DC panel, which needs its own space. Both kits share the 391 W AC inverter, so the output limit is the same. Grid-connected solar offsets electricity while the sun shines. It does not supply backup power during an outage. Free shipping in the US, except NY, ME and VT. Check your state's rules.
