balogunsam: I've used that controller before. Provided the amps of the panels does not exceed the controller specs, then the installer used a fake copper cable that is heating up and damaging it, an undersized gauge with the same heat issues, or he is not screwing the cable properly in place, partial contact which can still cause same heating issue. |

Queed: Interesting angle..you seem knowledgeable about this stuff. Nice. However, wouldn't PF come into play when one is considering conversion from apparent power to real power? Because in my measurements, I'm comparing volt-amperes with volt-amperes. |

Trippledots: You mean you exceeded the maximum wattage rating for the cc? In his case with a 60A cc, the maximum PV wattage supported should be (12V * 60A) 720w. His installer fed the cc with (180 * 6) 1080w from the panels. Is the cc a pwm or mppt? |

Hello family, I think the time has finally come. I need the rough estimate of what it would take me to go completely off grid. My 2.5Kva generator powers all appliances in my apartment effortlessly including a 205 ltr freezer and a 180ltr fridge,,1000W home theater system,smart 50 inch tv,2 ceiling fans,4 standing fans,and numerous energy saving light bulb(which are not always on simultaneously),but whenever I want to use the microwave I switch off all appliances I need something similar from the solar/inverter set up. If I can also include something that can power 1.5HP regular AC also, I don't mind the cost without the AC. Please I need the exact cost that would take me off grid, This new tariff rate is killing me. |

EduTechTainMent: Those panels can't output 60amps, if it was connected more than the max input volt of the CC, the equipment would have burnt out or self protected and not worked at all. |

EduTechTainMent: In some controllers, you can exceed the maximum rated wattage with no damage to the controller, but the issue is that the excess panels are just there doing no job. Eg if the maximum rated by a 60A controller @ 12v is 720w and you have 1200w PV connected to it. At most what you'll get out of it is that 720w, the remaining 480w PV is just there outside doing no work. 4 Likes |

balogunsam: Your Solar Charge controller is a Cheap PWM type, they get so hot as they can barely handle what they are rated for. this 60A CC shouldn't handle more than 20 to 30A input as its elcheapo.. 6, 180W Panel is pushing close to 60A to the Charge controller that's why it gets burnt. Get an MPPT charge controller and change the Solar configuration to 3s2P. current will be reduced at input and you will be able to charge your batteries more efficiently. |

Hello great people🫡🫡🫡 Good morning to y’all, please I need your opinion about this. I have a solar setup before using 6 pieces of 280w panel but now that I got a bigger battery I bought another 6 pieces of panel but now 300W. Should I connect the 6 pieces 300W I’ve just bought to the 6pieces of 280W I have with me before in the normal 2 series connection and then parallel them together afterwards or I should rather get a separate charge controller for the 6 pieces of 300W I’ve just bought and run the connection differently which will mean my hybrid inverter will be charging the battery and also the new charge controller I will be getting will also be charging the battery. |

RickyM: Incomplete data.. Provide the Panel data as well as the inbuilt CC data.. |
| Re: Solar Energy, A Complement To FTA by RickyM: 9:32am On Apr 04 |
Dam5reey:The old 280W panel output 30.8V and 8.2A while the new panel output 39.8-40.2V. I have not get the new charge controller so I can’t say what the cc is. My hybrid inverter has an inbuilt charge controller that charges my battery before. A picture of my inverter specification is attached below

| Re: Solar Energy, A Complement To FTA by Dam5reey(m): 9:42am On Apr 04 |
RickyM: The Answer is simple Get an MPPT controller for the New Set of 300w panels.. Your Inbuild Charge controller is only 50A and PWM. interesting to know how you connected the 6, 280w panels.. the best efficiency is to connect all 6 in Parallel. but I doubt that's the case. If possible, Get 2 external controllers, 1 for the 280W set and a second for the 300W set. The inbuilt CC is not efficient enough.. 1 Like |
| Re: Solar Energy, A Complement To FTA by RickyM: 10:00am On Apr 04 |
Dam5reey: Thanks for the swift response. My old connection is 2 in series (60v 8.2A) consecutively making three pair of 2 panels in series then parallel them together making it (60v 24.6A)… in an ideal condition the panel won’t output 8.2A as that’s just its rating, the best would be that it output 21A but if I connect everything in parallel then that would mean (30.8V and 42A) which is still under its rating. Do you think 30.8V is enough for a 24V system? I will get a new charge controller for the 300W panels as you’ve suggested. MMPT charge controllers aren’t cheap and it’s efficiency difference ain’t that much according to the series of YouTube videos I’ve came across. |
| Re: Solar Energy, A Complement To FTA by Dam5reey(m): 10:11am On Apr 04 |
RickyM: Exactly my guess, You are only using 3 panels.. all these while.. A PWM controller provides your batteries with the maximum available current, wasting excess Voltage. So you connected 60V 24.6A to a PWM. Even in full Sun, it will supply your batteries with 28V at 24.6A. excess voltages or 3 extra panels wasted. But if you do it all in Parallel. You will have 30.8V at 49.2A input and your batteries will charge at 28V at 49.2A. Here you are pushing too much current, you need High Guage Wires, which is expensive! With MPPT, you can maintain the 2 in series and 3 set in parallel. With MPPT, you are receiving the same 60V 24.6A.. your batteries will receive 28V at about 49.2A.. because MPPT will converter excess Voltage to current. 2. When you say MPPTs are expensive.. and you are only getting 840 watts from a possible 1680w..? You can use PWM. But connect it properly and size the cable properly too. When I was using a PWM Controller on 24V system, I purposely Bought 280W panels with 30V VMP... and a higher current. Because I understand how to optimize each Device wether PWM or MPPT. it's all about understanding. 3. Yes, 30.8VMP is the sweet spot for 24V if you are using PWM. 5 Likes |

Dam5reey:Bleep!!!! It was connected that way by an installer. Thanks for the enlightenment, I can’t thank you enough!🙏🙏🙏🙏🙏🙏 I will get another installer to help out with the connection when the 300W set of panels arrive. |

I know this is not related here but I have checked NL no exact live thread that talks about AC. Please what’s the cause of this, I’ve called an AC technician to fix it, unfortunately it’s not up to a month it starts again and the werey is not ready to come back .

| Re: Solar Energy, A Complement To FTA by jonescosmos(m): 11:24am On Apr 04 |
funshyboi: WHEN YOUR AC LINE IS FROZEN, THIS IS WHAT IS LIKELY HAPPENING. This can be attributed to several variables. These include low refrigerant, refrigerant leaks, accumulation of dirt on coils, dirty filters, and other restrictions of air flow from your system. Perhaps you have noticed that your AC isn’t quite cooling your home the way it should. Temperatures are rising indoors and you go outside to check your unit and see if you can find the problem. Despite the summer temperatures, you notice that your AC line is frozen and covered in ice. One or more factors might be causing a frozen AC line. Poor Airflow over the Evaporator Coil When the evaporator coils on an air conditioning unit become too cold, the ac unit pipes freeze. This is the primary reason behind frozen AC lines. The evaporator coils inside an air conditioning unit are filled with refrigerant. A properly functioning AC system extracts the warm air from inside your home and sends it through your air conditioner, where the evaporator coils cool the warm air, then redistribute it back into the home. If the airflow leading into the air conditioner is obstructed, it can cause the evaporator coils to become too cold, therefore causing the copper lines attached to your condenser to freeze. Here are some common factors as to why an air conditioning system can develop poor airflow: Dirty Air Filter You should be changing your air filter on a monthly basis. If it becomes dirty and clogged, it will prevent air from flowing through the unit and allow the coils to freeze. Supply Vents are Closed Some homeowners assume that closing supply vents in rooms that aren’t being used will put less stress on their unit and lower their utility bills. However, this practice can limit air flow and lead air conditioners to freeze. Return Vents are Blocked Vents are also used to suck air into the unit and play an important role in proper air flow These can also become blocked and cause the unit to malfunction. Broken Fan or Blower A broken fan won’t be able to send enough air over the evaporator coil. The fan is responsible for not only pulling warm air into the system but also pushing cold air into the home through the ductwork and vents. When something goes wrong with the blower motor or fan, your AC system will stop working properly, it will become difficult to cool your home and your AC line could freeze. Dirty Evaporator Coil Just as dirt can block the air filter and cause problems, a dirty evaporator coil will also prevent proper air flow. Regular maintenance will help you avoid this problem. What to do: Regardless of the refrigerant leak cause, it’s nearly impossible for a homeowner to resolve the problem independently. Refrigerant is a dangerous chemical, and only professional technicians should handle it. Nevertheless, to troubleshoot any of these potential issues, follow these steps. 1. First, check your vents. These include the air vents that push air into your spaces and the return vents that pull air back through your AC system. Make sure they are clean, open, and unobstructed. 2 Then, check your air filter to ensure it is clean and allows air to flow through. AC system air filters will be inside of your return vents. When you open the vent cover, visually inspect the filter. If it is brown or covered in dirt and lint that you can see, it’s probably time to replace it. 3. Next, you’ll check the blower fan for your air conditioner. To do this, go to the thermostat that controls the AC unit and switch it from COOL to OFF. Then, locate the fan controls on the thermostat and switch the fan from AUTO to ON. When your fan is “ON,” it will blow air even if the AC isn’t running a cooling cycle. Doing so means more warm air will blow over the evaporator coils to help defrost the pipes. Leave the fan ON and the AC system OFF for 3 to 4 hours before turning the system back to COOL. 4. If you still see ice on the pipes after completing the first 3 steps, it’s time to call in experts. An AC technician can inspect your vents and the inside of your AC system to see if they are the cause of your issue. 2 Likes |
