This Pure Sine Wave Inverter is a combination of an inverter, battery charger and AC auto-transfer switch. Low frequency, low Idle Current, remote control.
Adjustable Charging Current: The max charge current can be adjusted from 0%-100% via a liner switch on the right of the battery type selector. This will be helpful if you are using our powerful charger on a small capacity battery bank.The liner switch can effectively reduce the max charging current to 20% of its peak.Choosing “0” in the battery type selector will disable charging function. 

AC/Battery Priority: Our inverter is designed with AC priority by default, when AC input is present, the battery will be charged first, and the inverter will transfer the input AC to power the load. The inverter can be easily customized to Battery priority via a DIP switch, When you choose battery priority, the inverter will invert from battery despite the AC input.

Auto Gen Start: the inverter can be customized to start up a generator when the battery voltage goes low.When the inverter goes to low battery alarm, it can send a signal to start a generator, and turn the generator off after battery charging is finished. The auto Gen start feature will only work with generators designed to work with this feature.

Protections: AC input over voltage protection/AC Input low voltage protection/Low battery alarm/High battery alarm /Over temperature protection/Over load protection Short Circuit protection (1s after fault)
/Back feeding protection. 

Main Features:

  • 4000W Low Frequency Pure Sine Inverter With Charger.
  • AC/Battery Priority Selector.

Well built unit! High Quality

Quality control so far is superior to most inverters on the market. Still in my own testing phase. Originally bought this for a truck camper project. But my home grid-tie with battery backup is 26 years old. (16KW) the 20 year AGM 24vdc battery cluster is now 22 years old. (I am on borrowed time) i had originally had 4kw one Trace SW4024 120 vac inverter. The AGM battery pack consisted of twelve 2 volt 1460 AH cells. They are 250 ft. From my house. (In a shielded steel building with the old inverters, solar charge controllers, wind turbine controllers etc. So this a backup to that. NEC requires ground connection and neutral to be connected at the first main circuit breaker panel. This split phase inverter says Do not connect output neutral to input neutral. Yes I tested the open voltage between input neutral and output neutral 33 vac exists between these two points. I tested with a 150 watt 120 volt conventional light bulb between both neutral and output neutral to ground .03vac. (not a problem) The low cost way around this is to isolate your main panel (now it is a sub-panel) and add a new main basic panal.

Highly recommend!
