  • Low quiescent current,low power "Power Saving Mode" to conserve energy
  • 4-step intelligent battery charging,PFC (Power Factor Correction) for charger
  • 8 pre set battery type selector plus de-sulphation for totally flat batteries
  • Powerful charge rate up to 110Amp,selectable from 0%-100%
  • 10 ms typical transfer time between battery and AC,guarantees power continuity
  • Smart remote control RJ11&RJ45 option
  • 15s delay before transfer when AC resumes,extra protection for loads when used with generator
  • Allows start up and through power with depleted batteries
  • 30A/40A through current ability
  • Multiple controlled cooling fan
  • Extensive protections against various harsh situations
  • 13 Vdc battery recover point,dedicated for renewable energy systems4000W Solar Panel Inverter Air Conditioner Solar System Home UPS Hybrid Inverter

On the DC end of inverter, there are 4 DIP switches which enable users to customize the performance of the device.

SW2AC Input Range184-253VAC154-253VAC
SW3Load Sensing Cycle30 seconds3 seconds
SW4Battery/AC PriorityUnitity PriorityBattery Priority

Low Battery Trip Volt:

The Low Battery Trip Volt is set at 10.0 VDC by default.It can be customized to 10.5VDC

AC Input Range:

There are different acceptable AC input ranges for different kinds of loads.It can be customized from 184-253VAC to 154-253VAC.

Load Sensing Cycle:

The inverter is factory defaulted to detect load for 250ms in every 3 seconds when SW3 setting positionl. In NIGHT CHARGER position, the inverter will stay in standby mode without sensing loads. It won't output any powereven if a load is turned on when working on battery mode.

AC/Battery Setting:

Our inverter is designed AC priority by default. This means, when AC input is present, the battery will be charged first, and the inverter will transferthe input AC to powerthe load.

The AC Priority and Battery Priority switch is available upon request. When you choose battery priority, the inverter will inverting from battery despite the AC input.
