TROUBLESHOOTING
Problem | Things to Check | |
|
| |
| 1. Battery voltage under load below 10 volts. Charge batteries. | |
| 2. Loose battery connections, open battery switch or blown DC fuse. | |
| Tighten connections or replace fuse. | |
| 3. Tripped circuit breaker on front panel. | |
No Inverter Output | 4. Thermal condition, excessive loads or inadequate ventilation | |
| caused overheating. Allow to cool. Ventilate the compartment. | |
| 5. Overloads or short circuit, check for excessive loads or shorted | |
| wiring. Disconnect loads. | |
|
| |
| Confirm that your volt meter is a True RMS meter. Standard volt | |
Low Inverter | meters will not accurately read the 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 - check both the AC and DC connections. | |
| 2. AC input voltage - low voltage input will result in low DC output | |
| current. Expect reduced charger output from generators under 3,500 | |
| watts. | |
| 3. Check power share setting if using a remote panel. | |
Little or No Output | 4. If Starter or Auxiliary battery is not charging quickly, check the | |
difference between the house battery and the starter battery with a | ||
from Battery | ||
volt meter. If difference is greater than 3.2 volts, the echo~charge will | ||
Chargers | ||
reduce energy delivered to the start battery. Check all connections to | ||
| ||
| the house and starter battery. | |
| 5. If there is no energy output to the start battery and the house | |
| battery voltage is above 13.0 volts, a thermal shutdown of the | |
| individual echo~charge has occured. The echo~charge will | |
| automatically restart when the temperature drops to a safe level. | |
|
| |
| 1. Microwave ovens will normally cook slower on inverter power | |
| because the modified sine wave output has a slightly low peak AC | |
Microwave Oven | voltage. | |
Cooking Slow | 2. Cooking speed will be determined by battery voltage. Low voltage | |
| results in increased cooking 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 inverter frequency is | |
Slow or Fast | well regulated at 60 Hz. The clock either counts the number of peaks | |
in the waveform or the number of times the waveform crosses zero | ||
Digital Clock | ||
volts. The circuitry that counts the zero crossing events is more | ||
| ||
| popular. The longer zero cross time of the inverter's modified sine | |
| wave may cause double clocking, resulting in a faster clock. | |
