Operating Instruction

0pen-package inspection

1. After opening the package, please check the attached parts and components, including the operation manual and checking whether the the inverter is in good condition? If found any inverter is broken or components missing, do not turn on the machine, feedback to the carrier or supplier.
   1. Note: Please keep the box and packing materials in case the use in the future.

Installation notice:

1. The products should be well-ventilated, away from water and corrosive and combustible gases.
2. Do not set it in a corner, ensure the bottom of the front panel, the rear panel fan outlet and the side of the machine are well-ventilated.
3. The environment temperature should remain 0-10°C.
4. If the machine operates under a low-temperature environment, it would cause water condense, only in an absolutely dry condition can the machine would work normally, otherwise, there will be an electric shock.
5. Install the inverter near the mains input socket or nearby the switch, to draw out plugs then cut off the mains supply once there is an emergency.

Attention:

1. The load should be turned off before connecting to the inverter and turned on one by one after connecting is completed.
2. The inverter should be connected to a socket with a corresponding current protection.
3. All power sockets should link with ground protection.
4. No matter input power cable inserts to the main socket or not, the inverter will also continue outputting possibly, turning off the inverter can not guarantee there is no current inside the machine. In order to make sure to cut off the output of the inverter, you should turn off all the switches and then turn off the main supply.
5. To load inductive appliances such as electromotor, displayed, and laser printer, the inverter capacity should be twice as loading machine’s rated power at least.

Care and maintenance

1. This inverter is low in repair rate. The battery of the standard model is valve adjusting, low maintenance, ensuring better life onlyby charging often. When connecting to mains supply, no matter inverter on or off, it still keeps charging for battery, and provide overcharge, over-discharge protection.
2. If there has been long time no using, please discharge then charge the inverter each 4-6 months.
3. Usually, the life span of the battery is 3-5 years. If any wrong with it, please ask professionals for changing. And do not change it by yourself.
4. Don’t change the single battery, changing the battery should according to the suppliers instructions.
5. Normally, the battery should discharge then recharge every four or six months, charging for it more than 12 hours after discharging.
6. At high-temperature area, the battery should be discharged and charging every 2 months and the standard charging time is 12 hours at least each time.

Note:

1. Before changing battery, must turn off inverter and disconnect the mains supply.
2. Remove metal object like ring, watch etc.
3. Please don’t put the metal objects on the battery.
4. This is the normal phenomenon, when connecting the battery wire, the wiring will appear at a small spark.
5. Be attentive to connecting between anode and cathode.

How to choose and configure PV panels
The following parameters can be found in the specifications of each PV panel:

• Pmax: Maximum output power (W)
• Voc: Open circuit voltage (V)
• Isc: Short circuit current (A)
• Vpm: Rated voltage (V)
• Ipm: Rated current (A)

PV panels can be connected in series or in parallel to obtain the required output voltage and current to meet the allowable range of the solar controller. When connecting PV panels in series, the total maximum voltage and current is:

When the PV panels that have been connected in series are connected in parallel, the total maximum voltage and current are:

• In either case, the total output power is the power of a single PV panel X the total number of PV panels. The criteria for configuring PV panels is that the total power should be equal to or slightly greater than the maximum allowable PV power of the solar controller (please refer to the technical parameter table ). The excess capacity of PV panels does not contribute to the capacity of solar chargers and will only lead to higher installation costs.
• The total Ipm of the PV panels should be less than the maximum charging current of the inverter (60A)
• The total Voc of the PV panel should be less than the maximum PV input voltage of the inverter (please refer to the technical parameter table).
  Example 1: Take a 12-inverter as an example to select suitable PV modules.
• Considering that the total Voc of the PV panel cannot exceed the maximum 150VDC. The total power should be equal to or slightly greater than 800W, we can choose the following specifications of PV panels.

The configuration scheme of the 12 V inverter is:
Every 2 PV panels are connected in series to form a group, and connected to 5 groups of PV panels.

10 PV panels are connected in parallel to the inverter.
