Jackery HomePower 2000 Ultra vs Jackery SolarVault 3 Pro Max
Technical comparison · All-in-one
Same battery size, same chemistry, same 800 VA feed-in limit: what separates them is how much solar you can connect. HomePower 2000 Ultra takes 2000 W on two inputs, SolarVault 3 Pro Max 4000 W on four.

The differences that matter
- Solar input 2000 W vs 4000 W → how much panel power you can connect (values as declared by the manufacturer).
- Two vs four MPPT trackers → four strings facing different ways, each regulated on its own.
- Expansion up to 8 kWh vs 15.12 kWh → how much battery you can add later.
- Grid charging 2.3 kW vs 3.68 kW → how quickly it fills during cheap-tariff hours.
Which one to choose
Choose Jackery HomePower 2000 Ultra if…
you have a few panels on one or two strings and expansion up to 8 kWh is enough. The trade-off: solar input stops at 2000 W, grid charging at 2.3 kW, and the app is needed for the first power-on.
Choose Jackery SolarVault 3 Pro Max if…
you have a roof with several orientations and want up to four independent strings, 4000 W in total, with expansion up to 15.12 kWh. The feed-in limit stays at 800 VA as on the other unit: what changes is how much sun you harvest, not how much you send to the grid. Without enough panels, the extra input goes unused.
