Quick Setup

1. Connect to 12V Battery

Attach red cable to battery positive (+) and black cable to negative (-). Tighten clamps firmly for safe high current contact.

2. Switch On and Read LCD

Power on the inverter. The LCD shows input voltage from the battery and confirms output is active. If error codes appear, refer to E1 to E5 troubleshooting.

3. Plug In and Monitor

Connect appliances to the dual AC outlets. Watch the output power on the LCD, staying under 1500W continuous. Allow startup spikes up to 3500W for inductive appliances.

Common Questions Before You Buy

What does each error code mean?
E1 = under voltage (battery too low). E2 = over voltage (too high). E3 = overheat (let it cool). E4 = overload (reduce load). E5 = short circuit (check appliance and wiring).
Will it run my RV fridge and microwave together?
Combined wattage must stay under 1500W continuous. A typical RV fridge (60-120W) plus 700W microwave fits comfortably. Don't run a 1500W microwave plus fridge at once.
How is this different from the 6000W heavy duty model?
This model is rated 1500W continuous (3500W peak) and physically smaller. The 6000W peak heavy duty model offers 3000W continuous, ideal for full kitchens or home backup.
Is 95% efficiency real?
Up to 95% under optimal conditions (mid range load, good battery). Real world efficiency typically ranges 85% to 92% depending on load. Still significantly better than basic budget inverters at 70 to 80%.
Does the cooling fan run constantly?
No. The fan is temperature controlled, only spinning when the inverter heats up. Saves battery and reduces noise during low load use.
