What does hybrid and battery ready mean?
A hybrid inverter manages panels and battery together: you can install it right away with PV only and later add Huawei LUNA2000 storage without changing the inverter. The battery stores surplus solar energy and makes it available in the evening, increasing self-consumption and energy continuity.

Frequently asked questions
Can I add the battery later?
Yes. It is a battery ready hybrid inverter: prepared to connect a Huawei LUNA2000 battery even after the initial installation, without replacing the inverter.
Can I install it outdoors?
Yes. The IP66 rating and natural cooling allow outdoor installation, with good resistance to dust and water. A position sheltered from direct sun is still preferable.
What is AFCI protection?
The AFCI (Arc Fault Circuit Interrupter) detects and interrupts electrical arcs on the DC side, one of the main causes of fire in PV systems: an important safety plus, especially on residential roofs.
How long is the warranty?
The warranty is 10 years, extendable up to 20 years, in line with the Huawei standard for residential inverters.
What should be checked on delivery?
Check that the packaging, model and supplied items match the order and show no visible damage. Keep the manual and documents, and do not energise the product if the enclosure or connectors are damaged.
