This is the foreline tube D level waveform when the power inverter was in 2000w full load.Įxpanding the foreline tube D level waveform when the inverter in 2000w full load. This inverter is designed to power about 2200 watt, the headline of this paper is 2000 watt is because the DC power supply maximum output current is 100A, so GoHz tested it at 2000 watt, for more than 12 hours testing, it can work well at 2000 watt, there would be no problem for the actual load at 2500 watt. This power inverter has a good starting ability, it only takes about 1 second for two parallel 1000 watt solar lamps.
Due to the EG8010 programming reason, the power inverter will continuous work after a few seconds if the power supply is not cut off. Short circuit protection is also set about two seconds to turn off the output. Adjust the inverter power limitation potentiometer, limit the maximum power at 2500 watt, (a little greater than 2500 watt), the power inverter works for less than two seconds before it turn off the output. Maximum connected load was 3000 watt for approx 10 seconds, due to the DC power supply limitation (paralleling a large DC battery and two small batteries), GoHz did not continue test it.
This was a full load test on the power inverter, two water heaters, about 2000 watt, the water was boiling completely. The dead zone time was a bit long (1uS), where the zero-crossing point did not look good, in order to ensure the safety of the tube, GoHz did not adjust it. The SPWM accuracy of EG8010 was not high enough waveform, so the inverter output was not good enough as pure sine wave. The picture was taken in short-circuited. If the main board is beyond repair, then a brand new inverter-board will be installed.Few days ago, GoHz made a 24V 2000W power inverter in home, sharing some design schematics and circuit diagrams. When the error appears you have to return the inverter to the manufacturer. There are 3 voltage categories for off grid inverter: 100Vdc, 145v and 500V.Įrror description in the manual: Bus Soft Start Failed.

You can purchase the right combiner box online, before you do that check the max PV voltage of your inverter and the manufacturer will install the correct SPD devide. It is important to mention that all surge protection devices must be earthed following the wiring insructions. The latter is usually part of the consumer unit and requires only 2 positions in the enclosure. The best practise in electrical installations is to install the SPD’s in a PV DC-Combiner box (between solar panels and inverter DC input) and a single phase or three phase SPD at the AC-output of the inverter. If your installation is protected by surges in voltage then your warranty will not be invalidated. To avoid such problem, we would also recommend installing the external SPD for PV input and AC input.Īdding surge protection devices will reduce the risk of getting 09 error. It could be due to the high AC surge or PV surge to damage these sections. Hence, DC-DC MOFSET and Inverter IGBT are also frequent failure components. The inverter converter the DC power to pure AC sinewave. In most cases, if the Inverter’s IGBT or DC-DC MOSFET are damaged then the inverter always reports the Error 09 alarm. The inverters have internal overvoltage protection but the actual protective devices have also their absolute maximum limit.
