Sapiosexuality: This is SAKO SUNON PRO, maybe Low Input Voltage. Whenever you see low output from your panels, always check the PV Input Current & Voltage; then multiply both to see if it matches what you see as the output in Watts. 1 Like |

kristien4: If the battery is less than 3 months you installed the system, you can add more batteries, provided you buy same battery Ah, model and ensure they are same voltage before you connect them together. |

TechGeek777:Thanks. It's up now to 1kw. I was only looking at the battery input in the first place. |

Dam5reey1: Okay boss, you are very correct at bolded, but I just don't want to be more knowledgeable than the manufacturer. Was even surprised seeing 80A, was expecting 40A Max. |

Sapiosexuality: Sako Inverter is good, it's truly Axpert clone. |

TechGeek777:Axpert clone? Is that a good thing? Isn't Axpert another company? |

Re: Solar Energy, A Complement To FTA by kristien4(m): 9:49am On May 27 |
TechGeek777:@techGeek777 @Dam5ree1. The battery also has a c1 rating on a sticker placed on top, does that justify the 80A max charge?

kristien4: That's Discharge.. Again you have exposed more reasons why we shout LFP battery ![]() at C10 is where you get 200AH.. At C5 you get 182AH At C3 you get 166AH At 1C which you never even attemp. You will only get 132AH and Voltage would have sagged to 9.6V before you can achieve that.. 50A Max is the Bulk charging current just as stated 0.25CA. to prolong your batteries do only 20A, 0.1C charging 3 Likes |

TCD: They're pretty affordable and easy to install. They are available online at AliExpre55. Someone here, @ojeysky I think, uses Tasmota instead of Tuya, but I didn't go the Tasmota way cos of the flashing and programming it requires which I'm not adept at. For the Tuya, you only need the app installed on your device and also a WiFi router in your home and with data subscription if you intend to do remote monitoring and control. Although without data subscription, you can only do monitoring when you're at home and your device is on the same network as the switches. Attached are a few of the devices I have and the screenshot of the app interface on my device. 3 Likes

Dam5reey1:Na wa... me thinking it was 80amps charging current all this while, to give a safe gap, i actually configured the the batteries to charge at 50amps max, not knowing i was already maxing out the 50amps charging current. I reduced it now. I just dey suffer my battery since.. ![]() ![]() |

Sapiosexuality: It's possible the input from your panels to the controller not yet the sufficient voltage that your CC requires, which means you'll hwve to wait past "early morning sun" a while to get to proper sun 🌞. It could also be that the connection is compromised at some point. Consider the following questions: ° Did your installer rip/cut off the MC4 connectors on that panel and do a direct naked wire connection instead? Many unlearned installers do this and with time,exposure of the junction to the elements result in compromise and reduced/interrupted voltage flow to the controller. ° Are your panels premium brand or at least one of the good ones? Were they purchssed used or new? The not-so-premium ones have bad wires on them and also bad connection to their MC4s so that with time,same thing as above 👆🏾 also happens. ° Could your MC4 connectors have partial contact at some point along the connection btw the panels? ° Are the wires from panels to controller good? Did he use the recommended stranded wires and not "NEPA" cable like some would do? ° How secured is the connection to the terminals of your charge controller? Note that in such cases of cases as above scenarios, you may even see the correct voltage expected from your panels displayed on your CC, but you won't be seeing any amperage or powee goung into the battery. 1 Like |

Dam5reey1: He didn't provide enough information. 0.25CA(25%) should ever be the highest. 50A * 48v = 2400w. Unless he's prioritizing solar input during the day, he should add more batteries to parallel it to 4s2p (if setup is less than 3 months). 20A * 48v = 960w (This is too small the way I see his load and pv capacity) 0.15CA(30A) or 0.2CA(40A) is the best he should charge. He should have asked these questions before buying Panels. Due diligence is required when dealing with RE. 1 Like |

kristien4: If Solar is only solar for charging. Leave it at 50A. Most time it won't reach, as you can see at 3900w PV input your load is taking 2000w and reaming going to battery which in return battery are only. Charging at 28A.. which is fair. Only time you will be boiling is when load is not that much. But set grid to charge at 20A and use CSO- which is Solar charge during the day and Grid during night. 2 Likes |

Xanderone: What I use is sonoff, it has its own firmware/app which works fine but I had to flash some with tasmota for integration with nodered. There is no nodered module that works with sonoff without internet.(Don't know if such module exist now though) 1 Like |

ojeysky: Each time you talk on those stuff,you lose me at the point where you mention "flashing with Tasmota" and the "node red" thingy. 😁. I just log off at that point, because it requires some programming which sincerely I can't say I wanna even dabble into. My hands are full already and I fear that once I start dabbling into the realm of programming of any kind, I may be disappointed in myself if i dont catch up fast or if i give up along the way cos of the same problem dat precludes my foray into it - TIME. |
Re: Solar Energy, A Complement To FTA by Xanderone: 5:17pm On May 27 |
Sapiosexuality: Someone mentioned few posts back that appliances may stop working if put in storage for a long time without use. Is this why you made that statement - (deform for lack of use)? I have a Bluetooth energy meter that I retired/disconnected from the set up about 2 years ago and actually intended to sell it that time. I later put in storage. Few days ago, I tried to reconnect it and found out the screen backlight would not work. I even thought the monitor was bad, but I was able to shine light at some angle and realized it was the backlight. This is something working perfectly before it went into storage. Pray tell, it this school of thought so valid? I fear cos I have spare inverters (12v, 24v, 48v) in storage for use as back-up on days when repairs (God forbid) needs to be done on main units.

Xanderone: Nevermind about the tasmota aspect sonoff works perfectly off the self just like Tuya. Tasmota is a different firmware entirely that can be used on sonoff if one does not want to follow come firmware 1 Like 1 Share |
Re: Solar Energy, A Complement To FTA by Compliant(m): 5:48pm On May 27 |
Greetings all. Some weeks ago lightning destroyed my 3.5kva inverter and having waited for 1 week to get it repaired , the repairer said the board is bad and it will cost around 140,000 to 160,000 to get a new board and it will also take time as they will have to order it from lagos meanwhile i am in abuja. So i decided to get a secondhand 4kva inverter. It was installed 4days ago but my issue now is that with my formal inverter with nepa light the battery will be fully charged in less than 24hours BUT this one that is just installed have being on nepa light for 3days and not full charged Please what could be the problem? Kindly note that the formal inverter normally charge like phone charging .i.e it add bars continuously until fully charging but this one have being charging from buttom for days now Is the inverter bad? Is the connection wrong? Is this bow some inverter charge? Please help out Thanks |

Xanderone: This is very true. My 8 x 18650 charger/analyser that I bought and never used have failed to work. My Reolink 5MP camera I bought and kept for like 2 years (forgot I had it ![]() Same thing happened to my heart rate monitor I bought and never used. Remembered the other day I was doubting the rate my watch gave after an exercise ![]() All these devices no longer works after about 3 years of it been left in their pack Can anyone explain why this happens? These days I'm now using every electronic I have. Don't want to be caught lacking again ![]() |

The internal components of electronic devices and gadgets degrade over time. In addition, some external pollutants and other elements can accelerate the shortening of shelf life. Humidity, dust, and high temperatures are common factors affecting electronics... mctfopt: 1 Like |

Xanderone:I don't know if it's valid for Charge controllers but It's certain for most machines around us. They all need a certain level of periodic servicing not to break down. Even the human muscle atrophies from lack of flow of blood/inactivity. |
