Important Safety Instructions

As an AC power supply equipment, the inverter’s AC output is the same as the household power plug’s. The inverter’s AC output should be treated with caution; otherwise, there will be a risk of electric shock! When using, please note the following:
Attentions:

• Connect the DC input according to the requirement strictly. The Power inverter has a relatively wide DC input range. Still, too high or too low DC input may cause problems even destroy the inverter.
• A reverse polarity connection will blow the fuses in the inverter and damage the unit.
• Do not expose the inverter to a humid, flammable, explosive, or dust environment.
• Keep the inverter out of children’s touch.
• It is recommended to connect the inverter input terminal to the battery. Calculate the minimum capacity of the battery (expressed in AH) in the following way: 5times of the rated power of the inverter/ battery voltage. If for testing  purposes, the user should select DC power supply current at least twice greater than that of the inverter rated input to keep normal inverter operation. Using a DC power supply for testing may cause damage to the inverter.
• When the inverter works continuously, its surface may become very hot; please ensure the air ventilation clearance around the inverter is more than 10cm. Keep away from the material or device which may suffer from high  temperature when the inverter is working. Do not install the inverter in an airproof location and keep enough space around the inverter.
• Connect the protective grounding to the ground. The cross-section of the wire should not be less than 4mm².
• The wire connection between the battery and the inverter should be less than 3m, and the current density should be less than 3.5A/mm² . At this time, the inverter is running at full load. If the wire length exceeds 3m, please reduce the current density.
• A fuse or breaker should be used between the battery and the inverter. The value of the fuse or breaker should be twice the inverter’s rated input current.
• Do not connect the battery charger or similar devices to the inverter’s input terminal.
• Do not put the inverter close to the flooded lead- acid battery because the terminals’ sparkle may ignite the hydrogen released by the battery.
• It’s an off-grid inverter. Do not connect the AC output terminals to the grid or electrical source; otherwise, the inverter may be damaged.
• This inverter can only be used singly in parallel connections. The series connection will damage the inverters.
• Risk of electric shock, don’t touch the output port when the inverter is working. The output is forbidden to connect to other power sources or grids; otherwise, the inverter will be damaged. The inverter must be turned off when connecting the load.
• Please do not attempt to repair the fault inverter by yourself; otherwise, it may lead to a severe accident. Don’t hesitate to get in touch with the manufacture’s engineer.
• SP power series is only suitable for civil applications, not for industrial applications.

Introduction

SP Power series is a pure sine wave inverter that can convert 12/24/48VDC to 220/230/240VAC (or100V/110/120VAC). Industrial design has a wide operating temperature, high reliability, and high efficiency compared with civil design. Simple appearance and lightweight make it easy to install and operate. The wide input voltage range is ideal for solar system applications. This inverter is especially suitable for civil applications, such as household emergency lighting  systems, vehicle-mounted systems, small field power supply, etc.
Features:

Wiring

Operation Steps:
Step 1: Turn the power switch of the inverter to OFF
Step 2: Disconnect the input breaker or the fuse between the inverter and battery. Connect the battery terminals (‘+’ with the red line and ‘-‘ with the black line). Do not connect the poles by contraries.
Step 3: Use the cable no less than 4mm² to connect the inverter’s grounding terminal to the ground.
Step 4: Connect the plug of AC load to the inverter AC outlet
Step 5: Switch on the input breaker or the fuse between the inverter and battery; turn on the power switch to start the inverter. If the blue indicator is ON, turn on the  loads one by one. Check the operation state of the inverter and loads.
Step 6: If there are different loads, the loads with higher startup current should be turned on first, such as television. After the loads work stably, turn on the loads with a lower  startup current, such as an incandescent lamp.
Step 7: If the Fault indicator is red and the buzzer alarms when turning on the devices, please immediately switch off the loads and inverter.

Maintenance

The following inspections and maintenance tasks are recommended at least two times per year for best performance.

• Make sure no block on airflow around the inverter. Clear up any dirt and fragments on the radiator.
• Check all the naked wires to ensure insulation is not damaged for serious solarization—frictional wear, dryness, insects or rats, etc. Repair or replace some wires if necessary.
• Check and confirm that indicator and display are consistent with required. Pay attention to any troubleshooting or error indication. Take corrective action if necessary.
• Confirm that all the terminals have no corrosion, insulation damage, high temperature, or burnt/discolored sign, tighten terminal screws to the suggested torque.
• Check for dirt, nesting insects, and corrosion. If so, clear up in time.
• Check and confirm that the lightning arrester is in good condition. Replace a new one in time to avoid damaging the inverter/charger and even other equipment.

WARNING ： Risk of electric shock!
Risk of electric shock! Before the above operations, ensure that all the power is turned off. The electricity in the capacitance is completely discharged, then follows the corresponding inspections.

Disclaimer

The warranty does not apply under the following conditions:

• Damage caused by improper use or use in an inappropriate environment
• Battery voltage exceeds the input voltage limit of the inverter
• Damage caused by working environment temperature exceeds the rated range
• Unauthorized dismantling or attempted repair
• Damage occurred during transportation or handling
• Damage caused by force majeure
