Орнотуу жана орнотуу
1. Инверторду монтаждоо
Mount the inverter in a dry, well-ventilated area, away from direct sunlight, heat sources, and flammable materials. Ensure sufficient clearance around the unit for proper airflow, especially around the cooling fan vents.

2. Туруктуу токтун киргизүү туташуусу
- Инвертордун кубат которгучу OFF абалында экенин текшериңиз.
- Connect the positive (+) cable from your 48VDC battery bank to the positive (+) DC input terminal on the inverter.
- Connect the negative (-) cable from your 48VDC battery bank to the negative (-) DC input terminal on the inverter.
- Ensure all connections are tight and secure to prevent loose connections and arcing.
3. AC чыгаруу туташуусу
The inverter features dual GFCI 120VAC outlets. Plug your AC appliances directly into these outlets. Ensure the total power consumption of your appliances does not exceed the inverter's 700W continuous output rating.

4. Алыстан башкаруу (кошумча)
The inverter supports a remote ON/OFF control via the green terminal block. Refer to the detailed specifications for wiring instructions if using this feature.
Иштөө нускамалары
- After all connections are secure, switch the inverter's main power switch to the ON position.
- The inverter will perform a self-test, and the indicator lights will show its status.
- Plug your AC appliances into the GFCI outlets.
- To turn off the inverter, first disconnect all AC loads, then switch the inverter's main power switch to the OFF position.
Энергияны үнөмдөө режими
The inverter features an adjustable power-saving mode. Consult the full technical specifications or contact support for details on configuring this feature via the DIP switches or variable resistor.
Техникалык тейлөө
- Тазалоо: Мезгил-мезгили менен инвертордун сыртын кургак чүпүрөк менен тазалап туруңуз. Желдетүүчү тешиктердин чаң жана таштандыдан таза болушун камсыз кылыңыз.
- Байланыштары: Regularly check all DC and AC connections for tightness. Loose connections can cause overheating and damage.
- Батареяны тейлөө: Ensure your battery bank is properly maintained according to the battery manufacturer's instructions.
- Ички компоненттери: Do not attempt to service internal components. Refer all servicing to qualified personnel.
Проблемаларды чечүү
| Көйгөй | Мүмкүн себеп | Чечим |
|---|---|---|
| No AC output, indicator lights off. | Inverter not powered on, low battery voltage, faulty DC connection. | Check power switch, verify battery voltage, inspect DC cables and connections. |
| Inverter shuts down, fault indicator on. | Overload, over-temperature, input over/under voltage. | Reduce AC load, ensure proper ventilation, check battery voltage. Allow inverter to cool down. |
| GFCI outlet trips. | Ground fault detected in connected appliance or wiring. | Disconnect appliance, reset GFCI. If it trips again, the appliance or its wiring may be faulty. |
For issues not listed here, or if troubleshooting steps do not resolve the problem, please contact COTEC customer support.
