The SunGoldPower LFP 4000 Watt 48V Split Phase Inverter Charger is not a simple power inverter, it is a top high quality power inverter, built for running your whole house (small home), Business, RV System, Trailer or Boat Application, this inverter charger is perfect for your off grid system or an emergency backup supply.
Three in one product:
★ The inverter transforms 48V DC power stored by batteries to AC electricity that can power the tools and applicances.
★ It has a buit-in 40 amp battery charger which help the grid or generator to recharge the battery.
★ The transfer switch allows the product to automatically switch between shore power and battery power within 10 mili seconds.
The inverter charger can work with various batteries, like Gel USA, AGM, Lithium, LiFePO4, LFP batteries. If you want to disable the charging function, choosing “0” in the battery type selector.
The max charge current can be adjusted from 0%-100% by the charge current control knob. It is helpful if you use the inverter to charge a small capacity battery bank.
The AC priority and battery priority switch is SW5. If you choose AC priority, the inverter will switch to battery input in the event of AC power failure. Once the grid or generator restores power, the inverter will transfer to AC input and recharge the battery. For solar systems, it is better to choose battery priority mode.
The inverter has auto generator start feature. In battery priority mode, when the battery voltage goes low and utility power is unavaiable, the inverter will send a singal to start the backup the generator and take power form the generator. It will turn the generator off after battery charging is finished. This feature needs the generator must have auto start function.
This inverter charger is capable of delivering full rated 4000 watts with an exceptional 300% surge capacity for 20 seconds.The inverter peaks is at 12000 watts, which can effective power your electronic devices, household applicance and power tools, especially the tools and appliances with startup surges, such as refrigerator, freezer, microwave.
It is also perfect for off grid system or use AC power supply for home power emergencies, which can keep the power supply uninterrupted in the event of an power failure. It can detect the loss of power and switch over to get power form a connected battery bank seamlessly to keep the power supply constant.
Another popular application of this inverter is for RV and vehicle upfitting applications, such as powering lights and other appliances in an off-grid cabin. It also can provide electricity for a mobile business or mobile office, and running camping equipment.
During the emergency situations or natural disasters, the inverter can become a true UPS (Uninterruptable Power Supply) with its seamless transition transfer switch (batteries required). For expamle, the inverter can run a sump pump to save the house from flooding or power to run a heater to keep plumbing pipes from freezing.

Frequently Questions Answer
1. What's the AC output amps?
Dear Customer, output amps is 16A, load can't exceed 4000W when 240V AC load, load can't exceed 2000W when 120V AC load, because this is split phase inverter, the power will be divided to 2*2000W when 120V output, hope your kind understanding, thanks.
2. What is the maximum charging voltage for this Inverter?
Dear Customer, it will have over charge protection shutdown if it exceeds 62.8V, thanks.
3. Can it charge 7 modules of Nissan leaf battery? (56 volts 66ah) (1 module: 8v 66ah)？
Dear Customer, you could find the battery type selector in manual, you need to choose different switch position according to your battery voltage, please download manual from Technical specification of product page, in addition, the battery total voltage can't exceed 48V, thanks.
