To Next PageTo Next PageWhat to do if the overload fault (red light) is illuminated on Sima Inverter?
If the red overload light is on your Sima Inverter, it means that the power draw is exceeding the inverter’s maximum capability. You should reduce the power draw to stay within the inverter’s limits.
Why does the power indicator (green light) go out on my Sima SPV-1 Inverter?
If the green power indicator light goes out on your Sima Inverter, it could be due to a missing 12-volt power supply, possibly from a blown fuse, or due to an output overload, output short circuit, low input voltage, or the unit overheating. Check the 12-volt power supply and replace any blown fuses. Also, identify and fix any fault conditions affecting the inverter.
What to do if an over-temperature fault occurs in Sima SPV-1?
If you are experiencing an over-temperature fault with your Sima Inverter, it means the internal circuitry is getting too hot, possibly due to overload or poor air circulation. To resolve this, allow the inverter to cool down and ensure it has proper air circulation.
Why does an under-voltage fault (beep) occur on Sima SPV-1 Inverter?
An under-voltage fault with a beep on your Sima Inverter means the input voltage has dropped to around 10.2 volts. To fix this, make sure the input voltage stays above 10.2 volts.
How to fix a blown fuse in Sima SPV-1 Inverter due to overload?
If the fuse blows in your Sima STP-150 Inverter, it's likely due to an overload. Replace the blown fuse, but before using the inverter again, find out what caused the overload.
Read all cautions and warnings before installing and using the inverter. Professional installation is recommended for unfamiliar users.
Keep inverter away from children, heat, water, and flammable materials. Operate in cool environments (40-80°F).
Sima Products does not authorize use with life support devices or systems.
High-efficiency operation, thermal, overload, and under-voltage protection.
Do not use with certain battery chargers or devices with warning labels indicating dangerous voltages.
Mounting hardware for the inverter is needed but not included.
Mount on a solid flat surface with ventilation space, securing with proper hardware to prevent movement.
Connect to a 12V DC source (11-15V DC) capable of at least 15 amps. Use cigarette lighter plug.
Turn on the inverter with nothing plugged in. Check green light. Then plug appliance and turn on the inverter.
Use products drawing less than 150 watts. Exceeding this may cause shutdown or fuse blowing.
Multiply current draw (amps) by 115 to determine wattage (e.g., 0.9 amps x 115 = 104 watts).
Plug appliance into outlet, turn on inverter switch. Green light indicates operation.
Green light indicates normal operation. If off, check power supply or fault conditions.
Red light illuminates when current overload fault is detected, exceeding maximum capability.
Unit beeps and shuts off if input voltage drops to 9.6V to protect the battery.
Unit turns off if internal circuitry gets too hot due to overload or poor air circulation.
Unscrew plug tip, replace blown 15A fuse. Never use a fuse greater than 15A. Remedy cause of blown fuse.
