Editorial verdict

The whole-house backup option for long power outages, not just the basics.

Best use case

A household that depends on large appliances and wants real backup during long power outages, with the ability to recharge from solar panels while the grid stays down.

The 3600W output (4500W with X-Boost on a single unit; 7200W joining two with the Double Voltage Hub) and solar input up to 1600W make it suited to running large appliances during long power outages, even while the grid stays down. It's expandable up to 25 kWh by adding extra batteries or a smart generator.

At 45 kg, international shipping is more expensive and harder to manage than lighter units in the catalog.

Pros

  • Solar charging up to 1600W: recovers fast even with the grid down
  • Expandable up to 25 kWh with extra batteries or a smart generator

Cons

  • 45 kg: more expensive and harder-to-manage international shipping

Ideal for: A household that depends on large appliances and wants real backup during long power outages, with the ability to recharge from solar panels while the grid stays down.

Mandatory check with your shipping agency. PowerLight doesn't recommend shipping methods or determine whether a product can be accepted or shipped. Before buying, ask your shipping agency to confirm in writing that they accept the exact model, along with requirements, cost, and timeline.
