Once the lithium battery voltage is charged back to normal or over nomnal voltage, the charger will proceed
with the preset charging settings.
2.5.16 Other Features
Low Battery Voltage Recovery Start
After low battery voltage shut off (10V for 12V model or 20V for 24V model or 40V for 48V model), the
inverter is able to restore to work after the battery voltage recovers to 13.5V/27V/54V(with power switch
still in “On” position). This function helps to save the users extra labor to reactivate the inverter when the
low battery voltage returns to acceptable range in renewable energy systems.
For the models with Tesla model S module algorithms in position 9, the recover voltage is 23.5V for 24V,
47V for 48V models.
WARNING
Never leave the loads unattended, some loads (like a Heater) may cause accidents in such cases.
It is better to shut everything off after low voltage trip than to leave your load in the risk of fire. Nobody
wants to return home, finding house surrounded by fire trucks and naughty neighborhood kids toasting hot
dogs against his house.
Conformal Coating
The entire line of inverters have been processed with a conformal coating on the PCB, making it water, rust,
and dust resistant.
While these units are designed to withstand corrosion from the salty air, they are not splash proof.
3 Installation
3.1 Location
Follow all the local regulations to install the inverter.
Please install the equipment in a location of Dry, Clean, Cool with good ventilation.
Working temperature: ‐10℃ to 40℃(14℉to 104℉)
Storage temperature: ‐20℃ to 70℃(-4℉to 158℉)
Relative Humidity: 0% to 95%，non-condensing
Cooling: Forced air
Warning! Operation in a condensing environment will invalid warranty.
3.2 DC Wiring Recommendation
The battery terminal bolt size is M8.
It is suggested the battery bank be kept as close as possible to the inverter. The following table is a suggested
wiring option for DC cable with length from 1 meter to 5 meters.
