If your SamplexPower Inverter's low battery alarm is sounding, it's likely due to low battery voltage. To resolve this, recharge or replace the battery.
How to fix abnormal low battery alarm sound on SamplexPower SAM-250-12?
If your SamplexPower Inverter's low battery alarm sounds abnormal, it might be due to a bad connection or wiring. Ensure that you tighten all DC connections to resolve this issue.
What to do if SamplexPower Inverter has no AC output, yellow LED is lit and green LED is not?
If your SamplexPower Inverter has no AC output, and the Yellow LED is lit while the Green LED is not, it could be that the DC input is below 10 volts. Try to recharge or replace the battery to fix the problem.
Why SamplexPower SAM-250-12 has no AC output, yellow LED is lit and green LED is not?
If your SamplexPower Inverter has no AC output, and the Yellow LED is lit while the Green LED is not, it might be due to the inverter overheating and a thermal shutdown occurring. Remove or reduce the load, and then wait for the inverter to cool down.
How to fix SamplexPower SAM-250-12 when motorized power tool does not operate at correct speed?
If your SamplexPower Inverter's motorized power tool does not operate at the correct speed, it may be due to a purely inductive load. To address this, make the load not purely inductive. You can try operating an incandescent lamp at the same time as the motor.
How to eliminate TV/Radio interference (snow, buzz) from SamplexPower SAM-250-12?
If your SamplexPower Inverter's TV/Radio is experiencing interference such as snow in the picture or a buzz in the speaker, it could be that the appliance is too close to the inverter. Keep the inverter and antenna distant from each other. Use shielded antenna cable and connect the antenna with an amplifier.
What to do if SamplexPower SAM-250-12 Inverter has non-continuous AC output and red LED is blinking?
If your SamplexPower Inverter has non-continuous AC output, and the Red LED is blinking on and off while the Green LED is lit, the inverter output power is likely limited by an overload or short circuit protection circuit. Reduce the load or remove the short circuit.
Why won’t my motorized power tool start with SamplexPower SAM-250-12 Inverter?
If your SamplexPower Inverter's motorized power tool won’t start, it might be drawing excessive wattage and is incompatible with the inverter. If appliance does not start, then appliance is drawing excessive wattage and will not work with inverter.
What causes SamplexPower SAM-250-12 to latch up with red and green LEDs lit?
If your SamplexPower Inverter has no AC output (latch up), and both the Red and Green LEDs are lit, the earth fault protection has been activated due to excessive current leakage from the load. Unplug the faulted load.
