THE TRADE-OFFS

What stands out.
What to look into.

Reasons to shortlist it

  • 1800W rated output gives more appliance headroom.
  • Compatible expansion batteries can extend runtime.
  • Published 500W maximum solar input offers another recharge route.

Details to check

  • 1024Wh is not a whole-home energy supply.
  • Panels and extra batteries are additional purchases.
  • Boost modes are not the same as rated continuous output.

What might that mean at home?

With a constant 100W AC load, our default planning model estimates about 6.9 hours. This assumes 85% conversion efficiency, 8W inverter overhead and a 15% battery reserve, with no recharging. It is calculated, not measured.

Your appliances may use energy intermittently or need more power when starting. Enter their own values in the planner to compare this model with your intended setup.
