Q: I currently have a existing off grid inverter 48V5KW already with cut off voltage of 44V for charging lead acid batteries, could I use this inverter to work for Meritsun 48V100AH Lifepo4 battery?
A: Yes, if you use the charge model of lead acid battery to charge our Meritsun Lithium battery,it is also ok, just set the charge voltage,such as cycle charge 53.5~54V and float charge 51.5V~52.5V. In our experience,shallow charge and discharge will be better for longer the battery life.
Q: Can I program the AC-Input for charging the batteries? My idea is that I reduce the AC Power in the input, but on the output I have than more power because the rest of the power will be delivered from the batteries. As example 15% comes from the AC Input and 85% comes from the batteries?
A: Yes, our smart hybrid inverter is available to set the AC input and battery parameters via remote monitor according to your requirements.
Q: I want to buy Meritsun 48V Wall Mounted Battery for my house, but I am new for the Lithium battery, I do not know how many battery and inverter I need, could you pls offer suggestion?

You just let us know the load power of your home appliances and working hours. After that, Meritsun will provide the most suitable and affordable solution for you.
The following calculation way for you learning more information:
How many kWh battery required is depends on the total load power and back-up hours. For example, the required back-up hours is 5 hours, and total load power 2KW, 10kWh battery will be ok
The inverter power=1.2~1.5*total system load power
Q: For Meritsun ESS 48V200AH Lifepo4 Battery, the LCD state OV, why have this situation, how should I do?
A: As for this situation of 0V, two problems to consider and check:
1. The air switch do not open?
2. The battery is under protection?
Regarding the protection:
Overcharge protection: discharge the battery directly
