Little Elf series

 IP65 high protection solar drive

Product introduction

Little Elf series is a special inverter  platform with many good features.

It can support DC input directly, no need battery, with excellent MPPT controller, support water level logic control

can sleep and wake up automatically, adjust speed according to the temperature and sunshine.

Little Elf series also can support IP65 cabinet 1Φ220/3Φ220&380

We can provide abundant optional parts, such as PV/AC auto-switch module

boost module for ≤ 2.2kW, optional GPRS part for monitor(Apps & Website).

Multiple protections(Reverse connection/Over voltage/Overheat…)

Introduction

(1)Reduce the PV panel quantity

Because the general solar inverter need high DC input voltage.

(2)Support single phase pump.

For the civil water pump, many motors are single-phase, but the solar inverter in the market don’t support single phase, only support 3-phase.

(3)Support AC/PV channels input together.

In the night, there isn’t PV input energy, the pump will stop. Some project needs to keep the pump working always.

(4)Support remote control

People can use mobile APP or website to monitor the running status, and control the system start or stop.

In order to meet the requirement from end-users, and solve the disadvantages of solar inverter in the market

Advantages of Little Elf series

(1)Be suitable for single phase and 3-phase water pump.

(2)Built-in MPPT controller and excellent MPPT algorithm for various photovoltaic panels.

(3)IP65 cabinet solution, meets various harsh outdoor environments, and can be installed in the outdoor directly.

(4)Support the boost modular less than 2.2kW, increase the PV output voltage.

(5)Support PV input and AC grid input together, realize the switching function automatically, without human intervention.

(6)Include water level control logic, avoid dry run status and added full water protection.

(7)Start smoothly for reducing the voltage spike to motor.

(8)Low start voltage and wide input voltage range give more possibilities for accepting multi PV strings configuration and different type of PV module.

(9)Digital intelligent control can flexible adjust and set pump’s speed range. In addition to soft start function also can provide lightning protection,

Over voltage, over current, overload protection function.

(10)Support GPRS modular, can operate the system by website platform or mobile phone apps.

（11）IP 65 dustproof and waterproof rating

（12）With anti-the function, full security
