Guys, please how do i arrive at the wattage consumption of the TV in the first pic.

For the second one, does it imply the regular consumption is 135w?

For the first, operating range is wider hence I think the 2.1A is probably the maximum current at the least voltage of 100v which makes it 210w max

For the second 135w I expect is the maximum and 75w is the regular (typical).

Disclaimer: wait to get confirmation from the gurus on this, I may be wrong

That's about right for both scenarios stated,

What I can't collaborate fully is the maximum power at lower voltage ....

but according to power law .... It's plausible.

Harmattan season is here again

Some installations might go under in coming months, while some with forward thinking owners or system managers sort for ways to prevent their investments depreciation.

Recent survey has it that "solar system loses about 30% of power production due to debris, bird poo, decaying leafs, and dust"

Be forward thinking today and request for a system check up and maintenance

I used the lowest voltage and maximum current to determine the maximum power that the device will consume. So depending on the TV settings at 100v it could require up to 2.1A but the current will be lower at higher voltage. In naija case where we use 230v(220-240) even if all the TV features are utilized 100%, the current won't be up to 1A thereby keeping power within the 210w max

Your invictus inverter seems to work on an algorithm that does not factor in higher voltages to the batteries during charging. Inverters are meant to compensate automatically and not allow working on a premise that if 48v DC imput =240AC output, then 56v DC should equal 300v AC!!!!


ok, thanks.that should be it, because everything works fine when their is no solar panel input
however am still looking for the manuals of
1. invictus inverter
2. yohako mppt charge controller

Please I have luminous 850va hybrid inverter and I have 2(300wats) solar panel, will it work if connect it directly to inverter as I did not have money for CC now
Re: Solar Energy, A Complement To FTA by dejidotun2000(m): 9:18am On Nov 30, 2020
Don't do it !

850VA inverters are usually powered by a 12V battery while 300W panels will deliver 36V. The high voltage will damage your battery in no distant time.

If your panels were 4 no 150W rather than 2 no 300W, you may have been able to get away with it.

It can't damage his battery as he is not connecting it to them directly, the charge controller inside the inverter will regulate the voltage albeit inefficiently, better he uses an mppt controller when he has the cash

As I understand it, the inverter in question is not a hybrid(lacks an in-built charge controller).

His intention is to charge the battery with the panels and he can do that only if the battery is in parallel with solar panels and the inverter.

Luminous 850VA is definitely hybrid as I own it too; although I don't use it no more. It has pwm cc

I thank you all, the inverter is hybrid in which I can connect it to the panel direct. I just want know experience of people that has used it before.

Good evening everyone. Kindly assist a new inverter user. Just got a 48v inverter system installed in my home by an inverter installer, but I would like to confirm the best charging settings for the batteries just to be on a safe side.
Please what should the charge settings be for the batteries in series 48v?
Bulk:
Absorb:
Float:
And which is better between 20A or 30A for charging the batteries through the inverter utility current?

modified: just incase you're thinking the batteries are installed on the floor, no there is a battery rack. I took the picture when it was just removed from the carton and placed on the floor during installation.

Good evening all,

I would like to know which is the better way to use 2 pieces of 200AH 12V battery.

A

1. If the batteries are connected in parallel to get 12V 400Ah and used with a 12V inverter and appropriate CC or

2. Used with a 24V Inverter and connected in series to get 24V 200AH?

B

1. If fully charged, and with both arrangements connected to same load of say 500W, which arrangement would handle better and for longer time (assuming all other conditions are constant)?

First off a constant 500w load would quickly kill any set of 2 12v 200Ah lead acid batteries. You should max out at 200w (100w load per 12v 200Ah) if you wish to help the batteries deliver their rated capacity and cycle life.


Think of batteries as a store of energy. An energy storage tank if you will.

In general the amount of energy stored and accessible is about thesame regardless of if your tanks (batteries) are connected in series or parallel.

In practice two 12v batteries in parallel are likely to last longer (not back up time but cycles) simply because the two batteries naturally stay in sync for SoC vs same two batteries in series where ultimately one battery drifts away from the other over time especially if no special arrangements in place to keep SoC in sync.

In practice, your average 12v inverter may not put out enough amps to recharge your batteries in an acceptable time so you may need two inverters in parallel or an extra smart charger.

A 24v inverter should have marginally better internal efficiency vs 12v but this is not a given.

If you had to incorporate solar, you would find that for the same PV array and similar products used, a 12v nominal system is most expensive and complicated to setup, a 24v nominal system is cheaper than 12v but the 48v system would likely be cheapest of all and allow you to harvest most power with minimal equipment deployed.

Overall, the 12v system will be more stable and run for more cycles than either a 24v or 48v would under thesame conditions would. A decent battery balancing mechanism would put the odds in favor of the higher voltage systems but battery balancers as we know them today I judge insufficient. My preferred method for lead acid battery balancing is proprietary and not to be disclosed on open forums.
