You should follow the manufacturer charge specs unless you know better. I was speaking particularly about flooded batteries needing at least 14.6v absorb charge voltage. The spec sheet you posted seems to be more of an AGM battery like Quanta and not a flooded battery. I have yet to see a flooded battery where the original maker specced charging below 14.6v - never mind what the Nigerian seller or distributor says. Typically the manufacturer gives you a range of ideal charge voltages and you pick your own sweet spot within the range. babaegun: |

I need clarifications pls I use this Navigator NC2200 generator rated for 1000W/1100W. I intend using it to charge soccerpower 24v 1.5kva inverter First question is would it charge it properly considering the grid is very bad here. I measured the output of the generator and the frequency is about 44Hz i hope i wouldn't have issues charging the inverter. If there might be any, I intend using a 2Kva tec stabilizer on it. Would the stab correct the frequency issue?? Please i would appreciate your inputs and recommendations. Thanks. |

babaegun: Many marketers/distributors copy and paste most don't even have an idea what a charge profile is. Back in the day, I wrote engineers at Luminous India for the correct charge profile of their tubular battery and they came back with the usual 14.4-volt absorption. I think Niyi was spot on when he said they recommend a low charge rate for their batteries to ensure longevity at the expense of capacity. I personally used 14.6 for absorbing my batteries and 31v for equalization once a month. 4 years on the batteries are still in use (with a different users who is still my friend) 1 Like |

Re: Solar Energy, A Complement To FTA by isangjohnson: 2:03pm On Dec 29, 2022 |
bigrovar:If the specification sheet is unknown, I think a good CC can help to keep the charging within the limits. I set my Morningstar Mppt CC absorption at 14.7 but the CC always dropped the limits (target voltage) to 58.07, 58.19 at most with charging current of 19.0A to 20.3A. I also set float at 53.40 but CC would indicate battery voltage 53.28, target voltage 53.28 as well. |
Re: Solar Energy, A Complement To FTA by GeorgeD1(m): 2:18pm On Dec 29, 2022 |
isangjohnson: the above charging algorithm is just one out of many salient features that sets morningstar (tristar) cc head and shoulders above the pack. you can't go wrong with that charge controller. it may appear to be pricey but it pays off in the long run when you keep using your batteries year after year while others have changed their battery banks 3x in a row. |

This would be the effect of temperature compensated charging boss. Most decent CCs and inverters have it as part of the package. But while this temperature compensated charging is a great feature to have, it most certainly does not negate the need to set your charge voltage and other related parameters correctly for your battery type. If you set too a high a voltage, temp comp can only help you cook the battery a little slower by adjusting for your local temperature and if you set too low a voltage, temp comp will help you speed up the battery sulphation process (slowly strangling the battery to death) isangjohnson: |

Re: Solar Energy, A Complement To FTA by durodee(m): 5:16am On Dec 30, 2022 |
luvlyoracle:The only potential problem is not the frequency. The capacity too. The capacity of that generator (1.0-1.1kw) to effectively power and charge through a 1.5kva is suspect. Charging puts additional burden on the generator and putting a stabilizer on it cannot correct that. |
Re: Solar Energy, A Complement To FTA by NiyiOmoIyunade(m): 7:08am On Dec 30, 2022 |
There are a couple of things going on here. First off most inverters will reject a supply frequency below 47hz and this is as it should be. The generator output frequency can be easily adjusted - typically by turning a screw/adjustment knob to bring the engine speed to spec. You said you measured the Gen frequency - I hope you have a proper meter so that you can verify that you are now in the 50 - 52hz range after adjustment. Now can the generator successfully run your inverter charging and other loads? This depends a lot on the Generator actual capacity and state of health, the size of connected loads on the inverter and if you can adjust the charging current on the inverter. If you are able to keep your loads + inverter charging current within the Gen's run ability then all good. As a side note, people often erroneously assume that a smaller generator cannot support/power a large inverter - it depends on a couple of things. Take the case of a 3.5 - 4.5kva Gen behind a 3.5 - 5kva Sukam or similar spec inverter - the average load on the inverter in a typical Nigerian household is under 1,000w and the inverter can put out a max 800w ish of charge current - a decent 3.5kva Gen will take these loads easily. However replace the inverter with a similar sized Mustpower or Axpert type which can pull up to 4x the current and the story changes - the Gen will groan unless you adjust the charge current downwards. A good rule of thumb is if you have a 5kva Gen it should be able to power up to 60% of the capacity in watts so a good 5Kva Gen can easily support 3,000w of loads. If you can keep your inverter charge amps + loads on the inverter + loads direct on Gen within 3000w then things should run smoothly. By way of preaching the gospel - a premium inverter like Victron can separate the AC input from the invert stage such that I can run 5,000w of loads on the inverter AC out but only draw 2,000w from the AC input supply (with this one can avoid overloading a Gen or other weak supply) - this and a host of value added features justify the price premium on these inverters. luvlyoracle: 2 Likes |

Good afternoon house, please I'd like to be guided rightly, I hv a 3.5kva 48v luminous inverter, would want to buy other support systems to power a household using 1.5hp pumping Machine which would be used mostly during the day. Want to know like how many solar panels I can buy and ba3s needed to power it. Please note, the pumping machine would only be used during the day if possible to maximize output and not stress ba3s.

I am not sure that a Luminous 3.5kva would start up a 1.5hp pump successfully - it is not that 3.5kva is not large enough but rather that the Indian inverters (Sukam, Luminous etc) generally have poor surge handling ability. They tend to go into overload when a large inductive load tries to start up. But do test it and see how things go and then can begin to move from there. Cedarfarms: 1 Like |
