Product Introduction

PT330 series solar inverter.This product passed several years R&D to Solar photovoltaic field and then design this solar inverter.According to the characteristics of the working principle of solar PV panels and the power supply.This product has the following characteristics:

Technical Features

   1.Using advanced MPPT control technology, real-time detection of solar panels power voltage, tracking the highest voltage and current, charging to battery with the highest efficiency.

   2.Using shuttle center keyboard high accuracy encoder,controlling accuracy 0.01HZ,having multiresolution setting function, easy operation and use.

   3.Using multiple power supply design,power input can use solar energy photovoltaic DC power supply, can also be a single-phase, three-phase AC power supply,simple wiring.

    4.Using wide voltage design,The inverter can remain stable under high and low voltage work,strong adaptability.


    Solar inverter mainly used in no power or power unstable region of the hill afforestation management lead Water project, supply water for river on both sides of the vegetation, soil and water loss prevention water supply project, the barren hills groves and other economy content of irrigation,natural ecological protection area desertification control water supply. Supply water for lack of electricity remote mountain area, farm, school, hospital, factory and home. No electricity area or electricity Force unstable area covering the areas of animal husbandry and water, irrigate for farmland and greenhouse.

    Widely used in the desert greening, desert governance, agricultural irrigation, water supply, urban life Water, pump systems, water purification, seawater desalination, etc.

Installation Requirements

Variable-frequency inverter should be installed at a indoor place with good ventilation and used the wall-mounted method;moreover,there must be enough room between it and its surrounding article or baffle (wall).It is shown as the following chart.
