My solar system says arc detected and DC generator error. i have a powertech 4000s surge inverter and readout show 12.2 volts and operating lights are on but there is no power coming into my camp. Mate i have my solar the inverter is no fault but there's no output everyday b4 i can see everday how much klw loading a day i want ask a help if you know someone to help me check my solar coz the installer of my solar great solar i think already bankrupt so & the my solar still warranty tnx. If you have a five-watt panel in the above example you take 100 divided by .3 (300mA) and you come up with 333.3. My model no. A solar charge controller is an electronic component that controls the amount of charge entering and exiting the battery, and regulates the optimum and most efficient performance of the battery.Batteries are almost always installed with a charge controller. its running for 2 years. I have the same problem as this guy our reading on the meter is the same as last week even with all this brilliant sunshine we've had X only had the panels 2 years but no answers from the company when I try to ring them how do we check this the box has Elster / enphase on it. If you want to check and don\'t have an engineer around, you can disconnect the battery terminals and check. Thank you. All of a sudden when lightning stuck somewhere in vicinity the led of inveter turned red and was showing PV REVERSE. Please advise. A solar charge controller, also known as a solar regulator, is essentially a solar battery charger connected between the solar panel/s and battery. Many panels have blocking diodes built in but some do not. After implementing Solar solution I notice that whenever I on d breaker from the combiner the current raises to the acquired value but within a few seconds the current starts dropping until it reaches 0amps.will like to know if it's d charge controller faults or otherwise? We have not greeted power since 2/17/17 after Edison came to check the meter. What does 'Ground 1 fault PAC +0.0W actually mean other than it is not generating? They are used in off-grid and hybrid off-grid applications to regulate power input from PV arrays to deliver optimal power output to run electrical loads and charge batteries. with sun its 13.7v. Ideally to effectively charge a battery such as you have in the video, the output from the solar controller needs to be in the range 13.5 - 14V. On my solar inverter the indicator always shows that by 9.00am every it is fully charged, but as soon as night falls we do not have enough to turn on even one light bulb. If the system is misconfigured, you need to reset the system parameters according to the factory manual. This lasts for about 3 to 4 hours before in fails again. These are two old panels from 1995 that I initially wanted to avoid fiddling with. welcome, first you should disconnect he 26 and 55Ah batteries or you will overcharge some and possibly undercharge others. I have the inverter shut down and am not using it currently. Always only charge batteries with the same Ah rating, recommended max is 3 in parallel. As suspected, this was all down to the regulator not turning on due to the Vbat+5V it needed to start. Therefore, as suggested by Bennett, discard the charge controller and just connect the panel directly to the battery. SmartSolar MPPT 150/45 - Tr restart without app. The system has been in our family for 4 years. One cable comes out of the conjunction box and goes into the solar charge controller. is XPI-Lxxxx-B series. Good chance you killed your batteries. my inverter is not charging and writing " no sun" when the sun is shining and its very hot. Please check the voltage at battery terminals every 10 minutes. It directs the voltage and current hailing from the solar panels setting off to the electric cell. It tries to reset every 180secs but does not. Please help. Hi my new hybrid solar system does not find any voltage from the cells, before switching the cells on to the system, i can measure between 307 and 330 V form them, but when i switch them on the voltage drops to 2 V. can it be the connectors between the cells? RV battery bank with the alligator clips. However you still need a blocking diode, to prevent the battery from discharging to the panel at night. All battery cables of equal length (1m) and terminated with cable lugs or similar. Voltage reading from BATT screws on controller: 12.85V, Voltage reading from LOAD screws on controller: 12.85V, Voltage reading from PV screws on controller: 16.8V, 4 Concorde Sun Xtender 2580 batteries in parallel connected to bus bar, Charge controller connected to 100A busbar (one per polarity). thax, Use a mult-metre and measure the voltage from the PV, battery and inverter. Without a data sheet and/or schematic for the charge controller, it is difficult to troubleshoot anything.Given the specifications you have listed, it is almost certain that the solar panel could not do any harm to the battery. You can check by connecting the panels in series then shading one panel. The voltage may go upto 20v. In the simplest of terms, a solar charge controller regulates the power that is transferring from a solar panel to a battery. After that, it has seemed dead :-/ I disconnected the various cables to see if it happened again, but they all remained "dead" (no light). When the indicator light shows to be charging, the controller has connected the solar module to … Charging Issues - SmartSolar 100/20 - One Solar Panel (245w) - 12v System. To know for sure you must use a DC multimeter. A mppt 30a controller. what do I have to do?? My inverter shuts off immediately l turn it on. Any suggestions? Having a low-voltage disconnect (something that shuts your system down when your batteries drop to a certain voltage) will protect you in the future. Batteries are rated for voltage capacity, and exceeding that voltage can lead to permanent battery damage and loss of functionality over time. From a distance it looks as if the panel has shattered but if close this was not the case. For Further Reading – MPPT _Pdf If there is no voltage reading at the controller battery terminals, the problem is in the wiring between the battery and the controller. But that can be very low in poor light, and panel specs go out the window. When the system has gone off, the battery rises again to fully charged immediately and the same issue occurs when I power on the inverter. This system is small, only 660 Watts.
