Built-In MPPT Charge Controller
The built-in MPPT solar charge controller streamlines the system installation process.
Pure Sine Wave Inverter
A DC to AC inverter that generates a clean, stable, and compatible pure sine wave.
Battery Charger
An AC to DC battery charger that is compatible with a variety of solar batteries.
All-in-One Integration
The Hybrid Inverter is an enhanced iteration of the all-in-one system, incorporating additional features.
VP300 series is very economical pure sine wave solar inverter, Inbuilt with 80A MPPT charger; Solar/AC priority is configurable, when setting solar priority, solar will charge batteries as first priority, and AC can also charge batteries when solar charger current is too lower, in this way system charge is optimazed best. it enables inverter to operate with all kinds of home appliances.
