I noticed earlier this year (as I can monitor the system remotely via a WiFi card setup) that randomly, the PV voltage spikes to between 125 and 131 V. When this happens, the charge power from the PV drops to 150 W odd and the charger current to 3 A. This can happen randomly during the day and can sometimes stay at these levels for up to an ...
Strings of solar panels operate at high voltages, up to 600V or higher. Operating at these elevated voltages over many years can, in some cases, allow a current leak to develop through the cells to the aluminium frames of the solar panels and into the earth, resulting in a significant performance loss.
Solar panel components endure strong UV radiation and temperature changes daily. When the back sheet of a solar panel is cracked, it shows that the components were not well chosen. This can lead to water vapor entering the panel and causing damage to the solar cells.
Solar panel fault-finding guide including examples and how to inspect and troubleshoot poorly performing solar systems. Common issues include solar cells shaded by dirt, leaves or mould. Check all isolators are all on, and the circuit breakers have not tripped off. Check the grid voltage on the inverter display or app for over-voltage issues.
Check the solar system performance data on the app and website, if available. Check the solar panels for dirt, leaves, mould, or shade issues. Check the solar inverter for any warnings or faults. Check that the isolators are all on and that the circuit breakers have not tripped off.
Solar panel orientation and tilt greatly influence solar performance depending on your distance from the equator. In the southern hemisphere, the ideal orientation is north-facing (South in the northern hemisphere) at a tilt angle roughly equal to your latitude. For example, in Sydney, Australia, the ideal orientation is north-facing at 30 degrees.
Faulty Electrical Wiring If your electrical wiring on the roof is faulty or old, it can disrupt the efficiency of your solar panels by affecting electricity production. This happens because, over time, the wiring can develop problems like loose connections, corrosion, and oxidation. Even pests like rats can damage the wiring by chewing on it.

Only use solar panels that are of the same brand, type and model. Do not use optimisers. Nearly all optimisers contain an MPPT or other tracking mechanisms, which will interfere with the MPPT algorithm in the solar charger. The PV array is wrongly configured. For a detailed explanation of how to configure PV arrays and properly use MC4 splitters and MC4 combiners, see the …
The power from panels reached 2300w then dropped to 600w then back to 2400w and kept doing this cycle very fast (attached is a video). Someone please explain to me what''s wrong and how to fix this issue.
At about noon the solar output shown on the Tesla app suddenly and instantly spikes to about double the output and then remains on that higher output for the rest of the day. It then repeats this cycle the next day. This is totally consistent with one of the inverters not coming online until that time and sleeping in the morning. It''s kind of ...

Hi Tj thanks for taking the time to try to help me so it''s 2 rows of 7 panels center fed I did get ahold of enphase and they did change my grid profile but that did not seem to help I have noticed lately that my lights flicker on occasion and that''s when the solar panels go out I thought it was the solar doing that when it went out but I''m starting to think it could be the line coming to ...
Has anyone else experienced this on their Sky sensor that runs off of solar? Once every day or every other day, I''ll get this random drop in voltage (see image). It doesn''t last …
An arc fault in a solar system occurs when an electrical current jumps across a gap between two conductive surfaces, creating a brief but intense burst of heat and light. This can happen when there is damage or wear to electrical wiring, connectors, or other components in a solar PV system, creating a pathway for the current to arc.Arc faults ...
Has anyone else experienced this on their Sky sensor that runs off of solar? Once every day or every other day, I''ll get this random drop in voltage (see image). It doesn''t last more than 5-10 minutes, and the sensor continues to report no problem, then the voltage jumps back up to where it was previously. Not sure if this is ...

I have not installed all of my panels so I am not overcharging. I reset oven clock each time so that I know if power went down again. Not seeing anyone else with this issue so I think I got another batch of bad inverters. And I am not looking for people to dog on EG4, just opinions of other inverters that do not have these issues as I am off grid and can not keep …
I''ve noticed that randomly during the float charge, it will go from 15/16/17/18 watts, down to 1/2/0, then back up within 1-2 seconds. Also the amps will fluctuate 0.5 – 1.2 …
India is on the cusp of a solar revolution and we at Tata Power Solar have been right at the forefront, leading the move towards sustainable energy solutions. Investing in rooftop solutions leads to great savings, while protecting the …
3 · I had my first solar system with battery installed last week, and so far have been very impressed. However, it is doing something strange that I can''t figure out: randomly discharging for no apparent reason. It has happened twice now, on two different days at slightly different times. I''ve checked the inverter and there is no discharge ...

I''ve just got all my wires (solar connector splitter, 12awg solar extension cable) so I can connect my ac180 outside connected to 2 100w panels (2 ecoflow 100 watt pulling 20v with both). I''ve noticed the AC180 wouldn''t start charging solar on its own unless I took sleep mode off, but it''s still randomly clicking and stops charging for a minute or two.
