Configuració i instal·lació
1. Muntatge de l'inversor
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. Connexió d'entrada de CC
- Assegureu-vos que l'interruptor d'alimentació de l'inversor estigui en la posició OFF.
- 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. Connexió de sortida de CA
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. Comandament a distància (opcional)
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.
Instruccions de funcionament
- 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.
Mode d'estalvi d'energia
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.
Manteniment
- Neteja: Netegeu periòdicament l'exterior de l'inversor amb un drap sec. Assegureu-vos que les obertures de ventilació estiguin lliures de pols i deixalles.
- Connexions: Comproveu regularment totes les connexions de CC i CA per assegurar-vos que estiguin ben ajustades. Les connexions soltes poden causar sobreescalfament i danys.
- Manteniment de la bateria: Ensure your battery bank is properly maintained according to the battery manufacturer's instructions.
- Components interns: Do not attempt to service internal components. Refer all servicing to qualified personnel.
Resolució de problemes
| Problema | Causa possible | Solució |
|---|---|---|
| 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. |
