adrusa: i have monitored charging behaviour of smartphones, including premium brands, once the battery gets into the higher 70s and 80s, charging current drops considerably. and at 100% some current is still seen to be sent to the phone. Maybe to keep the phone alive or to sort of float the battery. but there is definitely some current derating as soon as the lithium cell nears full charge. 1 Like |

Trippledots: You are right, there is a reduction in the current the battery is taking as it gets charged and it's internal resistance increases. But, that is not the same as float. That is still bulk/absorption. If your phone is on, it uses some power and that will be supplied from your charger rather than the internal battery, so your charger may really never read zero. But, if the phone is off, you may see zero reading. When lithium battery is full, the current read zero. At least that is what mine does. 1 Like

ojeysky: Should've stated the current. At least 200A. Thank you very much for posting this. |

You got a shock when you touched the positive battery terminal. It wasn't because the inverter was not grounded. If anything, you will get a shock while touching the positive terminal because it is grounded ! Grounding prevents you from getting shocked only if you touch the metal casing. It's possible that the AC output of the inverter is somehow coupled with the DC input possibly through the transformer. Ceaser01: |

Re: Solar Energy, A Complement To FTA by Abdomox: 7:49pm On Nov 17, 2020 |
odimbannamdi: Exactly. In my situation, I drained the electrolytes to the recommended level as they were filled to the brim by Luminous staff. Most flooded batteries do suffer sulphation (also spelt as sulfation) because they've been in store for long period. Hence, they need equalization or "high voltage" charging immediately they are purchased. I did 6 hours of charging at 29.6v after draining the electrolyte to recommended level, and everything has been performing well. But I reverted to 28.8v afterwards. It seems our gurus are advising 29.6v as normal charge now. |
Re: Solar Energy, A Complement To FTA by Abdomox: 7:58pm On Nov 17, 2020 |
viperVIP: The battery is suffering from sulphation as stated up there. Get an inverter/charger that you can set the voltage....set it at 14.8v to charge for 6 hours or more. This will help "boil" the electrolytes and remove the sulphates on the plates. You can then keep charging at 14.4v or as advised by battery manufacturer. Sulphation causes battery not to charge properly and the battery cannot withstand loads when battery is not charging. Hence, you will observe sudden drop in voltage when there's light out or PV is off. |

Re: Solar Energy, A Complement To FTA by ojeysky(m): 4:11am On Nov 18, 2020 |
a4cube: I earlier gave you an example with 300w, you have to leave the 2 I have highlighted above out of it. However if you must use them. A. Typical non inverter AC will do 1000w and freezer maybe 200w. That's 2200 so just multiply earlier quotation in 7 folds. ![]() 1 Like |

NiyiOmoIyunade:I burst out laughing upon seeing this. My second solar RE installation had all loads twisted together at the inverter output. I was horrified to discover everything else was bundled together at the DB, bypassing the MCBs. Crazy stuff. These days, it's a norm to see such from a previous "oga, I can do it for much less" installation. 2 Likes |

DADAL: To have done 28kAH it's likely it will be more than 13 cycles in practice. You may need to check settings on your victron, though it may no longer be necessary as you've moved to LFP, also I guess you meant never gone below 70% DOD. Happy sales! |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 9:28am On Nov 18, 2020 |
Any MPP GK user in the house that has the capacity to check actual load on battery (not via the MPP interface) should kindly quote me. |

This has to be wrong info. Electric shock on battery terminal suggest that the inverter has an issue already. In my experience, earthing will take away those kinds of leakage current rather than allow it shock you. dejidotun2000: |
