2. Consignes de sécurité
Adhering to safety guidelines is crucial when operating power inverters. Failure to do so may result in personal injury or damage to equipment.
- Ventilation: Veillez à installer l'onduleur dans un endroit bien ventilé afin d'éviter toute surchauffe. Ne bloquez pas les ouvertures de ventilation.
- Dimensionnement des câbles : Use appropriate gauge cables (4 AWG or thicker for this model) to connect the inverter to the battery. Undersized cables can lead to overheating and power loss.
- Polarité: Always connect the positive (+) terminal of the battery to the positive (+) terminal of the inverter, and the negative (-) terminal of the battery to the negative (-) terminal of the inverter. Reverse polarity can cause severe damage.
- Mise à la terre : Properly ground the inverter chassis to a reliable earth ground or vehicle chassis.
- Surcharge: Do not exceed the inverter's continuous power rating of 4000W. While it supports a 7000W surge for 2 seconds, sustained overload can trigger protection mechanisms or damage the unit.
- Eau et humidité : Keep the inverter away from water, rain, snow, or excessive moisture.
- Enfants: Gardez l'onduleur hors de portée des enfants.
- Composants certifiés : This inverter features ETL-listed transformers, UL458-certified fuses, and FCC-approved anti-interference technology for enhanced safety.

4. Configuration et installation
Proper installation is critical for the safe and efficient operation of your inverter.
4.1 Choosing an Installation Location:
- Installez l'onduleur dans un endroit sec, frais et bien ventilé.
- Évitez la lumière directe du soleil, les sources de chaleur et l'humidité.
- Veillez à dégager suffisamment d'espace autour de l'onduleur pour permettre la circulation de l'air.
4.2 Connexion de la batterie :
- Assurez-vous que l'onduleur est éteint avant d'effectuer tout branchement.
- Connect the included battery cables to the inverter's DC input terminals. Ensure correct polarity: red cable to positive (+), black cable to negative (-).
- Connect the other ends of the battery cables to your 12V battery. Again, ensure correct polarity. Use 4 AWG or thicker cables for optimal performance and safety.
- Secure all connections tightly to prevent loose contacts, which can cause overheating.
- Connect the inverter's grounding terminal to a reliable earth ground or vehicle chassis.

Image: The inverter's compatibility with various battery types (GEL, SLA, LI, AGM, LifePo4, USER, FLD) is highlighted, along with a table detailing adjustable low voltage shutdown settings for different battery chemistries.
4.3 Remote Control Connection:
Plug the RJ10 cable from the remote controller into the designated RJ10 port on the inverter. The remote allows for convenient power control and monitoring from a distance.
4.4 AC Output Connections:
- Plug your AC appliances into the 4 standard AC outlets on the inverter.
- For high-power devices requiring a direct connection, use the 40A hardwire terminal. Consult a qualified electrician for hardwire installations.
- Utilize the PD36W USB-C and 3.6A USB-A ports for charging compatible USB devices.

Image: The inverter is shown in an outdoor setting, connected to a solar panel, demonstrating its ability to power up to 7 devices simultaneously through its 4 AC outlets, 2 USB outlets, and 1 40A terminal block.
