Well I have used other LF inverters, and I would say this one is far the nicest. Its quiet, doesn't make a fuss when its loaded up. I use 2kw on a regular basis and it is fine . The fan runs the whole time but its quiet. Was worried the first few times but its the norm now.
Love the adjustable charger on it 0 to 75amps.. so I can change it when I get less sun in the winter months.
I would highly recommend this little inverter for the price. I would expect to pay double for this quality.
I have an off grid system with 72kwh battery and 4kw solar, I will be adding a 1kw vertical axis turbine before the winter, just to give me a little boost.
Keep up the good work Vevor, I will definitely use you again , as I received the inverter 3 days after order. Not 10 weeks from China.as is the norm.
