TROUBLESHOOTING
Problem | Things to Check | |
|
| |
| 1. Battery voltage under load. | |
| 2. Battery connections and DC fuse. | |
| 3. Circuit breaker on front panel. | |
No Inverter | 4. Thermal condition, high powered loads or | |
Output | inadequate ventilation may cause overheating. | |
| 5. Overloads or short circuit, check for excessive | |
| loads or bad wiring connections. | |
| 6. Reset button oin GFCI outlet. | |
|
| |
| Confirm that your volt meter is a true RMS meter. | |
| Standard volt meters will not accurately read the | |
Low Inverter | waveform of the inverter and may read anywhere | |
from 90 to 120 volts. If a true RMS meter is not | ||
Output Voltage | ||
| available, check the brightness of an incandescent | |
| light bulb - if it appears normal, the output voltage is | |
| properly regulated. | |
|
| |
| 1. Wiring connections - check both the AC and DC | |
| connections. | |
Little or No | 2. AC input voltage - low voltage input will result in | |
Output from | low DC output current. Expect reduced charger | |
Battery | output from generators under 3,500 watts. | |
Charger | 3. AC reverse polarity - check for voltage between | |
| the incoming white and green wires. If 120 volts is | |
| measured, this is reverse polarity. | |
|
| |
| 1. Microwave ovens will normally cook slow on | |
Microwave | inverters due to a slightly low peak AC voltage. 2. | |
Cooking speed will be determined by battery | ||
Oven Cooking | ||
voltage. Low voltage results in increased cooking | ||
Slow | time. Support the battery bank with an alternator or | |
| ||
| other charging source for quicker cooking. | |
| 1. Digital clocks either employ an internal time | |
| base or derive their time base from the incoming | |
| AC waveform. The frequency is usually well | |
Slow | regulated at 60 Hz. The clock either counts the | |
Digital | number of peaks in the waveform or the number | |
Clock | of times the waveform crosses zero volts. The | |
circuitry to count the zero crossing events is more | ||
| ||
| popular. The longer zero cross time of the | |
| inverter's modified sinewave may cause double | |
| clocking, resulting in a faster clock. | |
