Grid inverter SUN2000 330 KTL-H1 Huawei is a solar inverter designed to maximise the energy performance of farm photovoltaic installations.

Technically, the inverter works with a three-phase grid, which is an optimal solution for both the power grid and direct consumers of electrical energy in households. It also has a series of DC and AC protections including double DC protection - intelligent disconnection at the string level (SSLD) and intelligent detection at the connector level (SCLD).

The application of Intelligent I-V curve diagnostics helps to find and identify low-performance PV module strings or malfunctioning ones, which shortens the time needed to locate a fault and repair it. The inverter ensures maximum efficiency up to 99% and is equipped with 6 advanced MPPT circuits with the capability to connect 28 PV strings, optimising the amount of electrical energy generated.
