The M3048BP and M5000H-48BP inverters will use solar or AC input power to wake up overdischarged
lithium battery by a boost circuitry.
When they detect a 0V battery, the charger will output a small current of 48Vdc voltage to awaken the
lithium batteries.
Once the lithium battery voltage is charged back to normal (over 48Vdc), the charger will proceed with the
charging settings of program 19 and 20.
2.4.16 Other Features
Conformal Coating
The entire line of M series 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.

Warning! Operation in a condensing environment will invalid warranty.
3.2 Unpacking and Inspection
Before installation, please inspect the unit. Be sure that nothing inside the package is damaged. You should
have received the following items in the package:
*The inverter x 1
*User manual x 1
*Communication cable x 1
*Current sharing cable x 1
*Parallel communication cable x 1
Mounting the Unit
Before connecting all wiring, please take off bottom cover by removing two screws as shown below.
Consider the following points before selecting where to install:
Do not mount the inverter on flammable construction materials.
Mount on a solid surface
Install this inverter at eye level in order to allow the LCD display to be read at all times.
The ambient temperature should be between 0°C and 55°C to ensure optimal operation.
The recommended installation position is to be adhered to the wall vertically.
