3. Asennus ja asennus
3.1 Sijainnin valitseminen
Valitse sijainti, joka on:
- Kuiva ja suojattu kosteudelta.
- Hyvin tuuletettu lämmön haihduttamiseksi.
- Cool, away from direct sunlight or heat sources.
- Secure, to prevent accidental movement or damage.
3.2 Akun liitäntä
Connect the inverter directly to a 12V DC battery bank. Ensure the battery cables are securely fastened to the inverter terminals and battery terminals. Use the provided red cable for the positive (+) connection and the black cable for the negative (-) connection.
- Yhdistä PUNAINEN battery cable to the inverter's positiivinen (+) terminal and then to the battery's positiivinen (+) terminaali.
- Yhdistä MUSTA battery cable to the inverter's negatiivinen (-) terminal and then to the battery's negatiivinen (-) terminaali.
- Ensure all connections are tight to prevent arcing and overheating.

3.3 AC-lähtöliitäntä
Plug your 120V AC appliances directly into the two AC outlets on the inverter. Do not exceed the inverter's continuous power rating of 2500W.

Figure 3.2: The inverter provides 2 AC outlets, a USB port, and a Type-C port for connecting various devices.
3.4 Remote Controller Connection
Connect the remote controller cable to the designated port on the inverter. The remote controller allows you to monitor and control the inverter from a convenient location.

4. Käyttöohjeet
4.1 Virran kytkeminen päälle/pois
To power on the inverter, press and hold the power button on the main unit or the remote controller until the display illuminates. To power off, press and hold the power button again.
4.2 LCD-näytön ymmärtäminen
The remote controller's LCD display provides critical information about the inverter's operation:
- Akku Voltage (DC Input): Näyttää nykyisen äänenvoimakkuudentage of your 12V battery bank.
- AC -lähtö Voltage: Näyttää 120 V AC:n lähtövoimakkuudentage.
- Power Output (Watts): Ilmaisee liitettyjen laitteiden nykyisen virrankulutuksen.
- Akun tason ilmaisin: Visual representation of battery charge (100%, 80%, 60%, 40%, 20%).
- Tilan ilmaisimet: Symbols for High/Low Battery, Overheat, Overload, and other fault conditions.

Figure 4.1: The LCD display provides comprehensive information on battery status, AC output, power consumption, and fault indicators.
4.3 Automatic Transfer Switch (ATS) Function
When both battery power and shore power are connected, the inverter will automatically detect the presence of shore power. If shore power is stable, the inverter will switch to draw power from the shore power source, preserving your battery charge. If shore power is disconnected or unstable, the inverter will seamlessly switch back to battery power. This transition typically occurs within 12 milliseconds, ensuring uninterrupted power supply.
4.4 Laitteiden kytkeminen
The inverter can power a wide range of 120V AC appliances and devices, including but not limited to:
- Smartphones, tablets, laptops (via USB, Type-C, or AC outlets)
- LED lights, fans
- Small kitchen appliances (coffee grinders, toasters, microwaves within wattage rajat)
- Televisions, entertainment devices
- Electric drills, small power tools
- Refrigerators, freezers (ensure starting wattage is within peak power capacity)
Always ensure the total continuous wattage of connected devices does not exceed 2500W. For devices with motors (e.g., refrigerators, pumps), consider their starting (surge) wattage, which should not exceed the inverter's 5000W peak power.
