@NiyiOmoIyunade

Just want a little clarification. If the manufacturer specifies 14.4V as the absorb voltage for flooded batteries. Is it safe to go the 14.6V as you asserted above? Will it not, on the long run, degrade the battery?

NiyiOmoIyunade:
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.

Ok. Noted. wrt the bolded.

The spec sheet is actually from a flooded battery.

NiyiOmoIyunade:
What flooded battery brand and sold locally by whom please?
Was that spec sheet generated by the original manufacturer or the local distributor?

nnadychuks:
Lead acid
Li-ion
LiFePO4
Which is the best among these batteries? I’m asking cos my Li-ion “Haustrom” battery died under one year

Here you go - https://addonigeria.com/tubular-technology/ . The manual is available at the link.

In addition, Eastman Tubular Battery has similar specification.

In fact, they have the same manual sef . Just different name.

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)

isangjohnson:

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.

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.

There are a couple of things
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.

durodee:

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.

NiyiOmoIyunade:
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.

Time to finally get my solar panels and charge my batteries from that as a primary source and no longer from discos.

NERC has increased tariffs again.

Try to buy electric units and you will get my drift

Cedarfarms:
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.

Thanks
