LFP inverter charger is used widely in off-grid solar systems. This pure sine wave inverter could charge the battery directly from the solar panel by solar controller, and then provide AC power for household appliances. In addition, another choice is using generators or utility power to charge the battery. This provides a very flexible combination for your home or RV power system, reducing cost effectiveness by using renewable clean energy.
This inverter can produce AC 120 (L1+N) and 240V (L1+L2+N) output at the same times, Between 120V hot wire and Neutral wire power is 2000W, between hot1 and hot2 Power is 4000W. when you choose the inverter, pls make sure the inverter power is 1.2 times than the inductive load power.The built-in battery charger accepts generator or grid power (AC 240V ) to charge the battery and power AC household appliances. .

- 9 different batteries type selector
Multi Functions
- Auto Generator Start: The inverter can start up generator when battery voltage goes low.
- AC/Battery Priority: selected by SW5.
- BTS : it can monitor the batteries for extended life and longevity.
- LCD Remote Control : Comes with 32 feet connection cable, control the power on/off,informative LCD display.
It is widely used for off grid system , RV or home power emergencies,In an off-grid solar system, your solar panels charge your deep-cycle batteries instead of powering your household loads directly. In addition to converting DC to AC power, the inverter charger can also assist in charging your batteries from an AC source like a generator.lets you take the RV off-grid and still use your refrigerator, lights and other appliances.
Warnings:
- 4000w 24v inverter charger should be only used for 24volt off-gird solar system with 240Vac input.
- This inverter is low frequency inverter with pure sine wave output.
- This inverter does not include MPPT solar charger.
- It can not be used in parallel and has no communication access for monitor.

install the 4000W 24V split phase 220V inverter approximately 3 month after receiving it.It came in good condition considering that it was an international purchase.The packaging was solid. Everything was in the box and as described.I was able to handle the issues that arise using the instruction manual. Now i have approximately 75% of my resident onsolar generated electricity including washing machine,toaster ovens, chest freezer and refrigerator, smart TVs etc. power tools such as power saw, grinder, drills.and accessories such as water pump. I am a proud first time DIY at solar PV. .With the experience i have with the 4KW split phase inverter I would recommend it.

I bought this inverter from the SUNGOLD website direct to take advantage of a sale that they were having but caught them when they were out of stock and simultaneously closed for the Chinese New Year celebration.After some back and forth communication they apprised me of the situation and offered me a bigger machine, but I stuck with the 4KW and waited until they were back in stock.I am very happy with the result. You can see from my installation that it makes a clean system for backing up my power here in Texas. We have been having problems with power outages - you might have heard - and I wanted to have a system that would keep my lights and a few high-priority circuits active and covered for an hour or two. In my case, I think that the system will actually keep my priority circuits alive for about 6-8 hours, but I just want lights for the first hour or two while I hook up the backup generator to run the well, freezers, and swimming pool (in case it is freezing again).The inverter has a ton of optionality and an easy-to-understand User Interface. I did not use the remote controller since the entire system is in a hall closet easy to access.I decided to use AGM batteries instead of Lithium for cost reasons and due to the fact that I don't expect a lot of cycles, and certainly not deep ones.
