Please check this photo, just find out R14(10M ohm )and replace it with a 1M ohm or 1.2M ohm resistor, or connect a 1M ohm or 1.2M ohm resistor with R14 in parallel, then the DC voltage will become higher.
Maintenance Instruction For LF 5.0 Main Board By Arrina | 05 July 2016 | 0 Comments There has small light in each mosfet board of main board.If all parts normal,the led light will be on.If have parts got fault, the led light will be off, then you just replace the mosfets board is ok.It is easy to remove and install the mosfet board :

In electrical engineering, power converter is converting electric energy from one form to another, converting between AC and DC, or just changing the Voltage or freqency, or some combination of these. A power inverter is an electrical or electro-mechanical device for converting electrical energy. This could be as simple as a transformer to change the voltage of AC power, but also includes far more complex systems. The term can also refer to a class of electrical machinery that is used to co...
Q: do the charge function to be connect with home AC110v source?  A: no. charge function is connect with battery and home AC 220v source, not Ac110v.
Q: what is the frequency of your grid tie inverter? A: our inverter's frequency is 50hz/60hz, auto detective.
Q: if I need to add controller between solar panels and inverter? A: no need, as our inverter already set up controller inside machine.  just connect solar panels in our inverter directly.
Q: why customer need use generator, to charge our ac inverter? A: the generator is AC output, this should be connect to our AC power cord, not battery, means generator is like home power AC source, and because generator's AC source quality is bad & dirty, will damage appliances if connect generator & appliances directly for a long time, through our pure sine wave power inverter, inverter will transfer the power to pure power
Q: I have received my item okay. There are to 12v inputs on the back of the unit, do you have to wire them both up or just use one set for one bank of batteries? A: Just use one set is ok, if you want to use big watt, you can use both so as to balance the electric amps.
Q: Hey I wanted to buy you inverter but what does it mean no universal plugs I was looking at the pics and I notice it didn't have regular inputs for a cord. So can it not take regular cords to plug in? Please let me know cause I really wanna buy                                                    A:  Hi, this is the photo of the output side, the sockets are univ...
