Product Description

Max 8KW Low Frequency Off Grid Solar Inverter Charger

Max 8KW Low Frequency Transformed Based off Grid Backup Inverter Charger



TBB Power - off grid low frequency transformer based hybrid inverter charger is an ideal solution especially designed for Solar Off grid, Hybrid, ESS - Energy Storage System, Backup power, UPS applications.


Kinergier Pro is a pure sine wave inverter generating a near perfect sinusoidal AC wave power
output that is very similar or even better to what you can get from your utility grid. Pure sine wave
can guarantee the correct function of sensitive equipment (computer, laser printer, TV etc.). Also,
your home appliances will work smoother, cooler and more efficient, such as fridge, microwave
and power tools.
Overload protection
When overload protection is trigger on, it will restart automatically after 60s. And after three
consecutive overload shutdown protections, the equipment will not restart automatically. At this
time, the user needs to manually restart.
Over temperature protection
When the internal temperature is too high, Kinergier Pro will enter into the over-temperature
protection. After the internal temperature returns to normal, it can automatically resume normal
Short circuit protection
