You can check Famicare; or one of these Ericsson chargers; am not a fan of cheap Souer chargers, Some charge up to about 14.6v, for a 12v battery and that is destructive for most Batteries in the long run

Thanks

As for the 14.6v thing, does it apply to all batteries? 'Cos some batteries have charge voltage of 14.4-15.0v or 14.3-14.7v written on them as the recommended.

You better off buying, say luminous 12v inverter about 50k with one 200ah battery at say between 70-90k. I guess it can serve or buy the 99k Luminous Delite Package

I want something inexpensive. My ma hardly watches TV so it is a waste to setup something large. I just want her to have light 24/7 and have means of powering TV if she decides to watch TV.

Hmmm...what's your budget?

The 32" TV alone consumes about 40-60w plus Gotv 12-18w
That's 78w using the upper range.
A 100ah costing about 40-50k should power these for about 6hrs all things being equal.
You will need an inverter which you can get for 15 -20k and an external charger for about 10k-15k (or do you want to use solar?)

It would have been easier/cheaper if the TV was a DC TV, then you will not need an inverter - only battery, external charger and DC bulbs.

That’s fine if it is stated that way, many people end up destroying thier batteries; having not to check those parameters well enough can on the long run damage the cells.

I have already installed two 10 watts panels(parallel), 12v 7ah battery, 10amp cc and five 5watts DC bulbs for light. I just want to incorporate inverter for TV.
It would have been easier/cheaper if the TV was a DC TV, then you will not need an inverter - only battery, external charger and DC bulbs.

I am contemplating 40-80watts panel, 300v modified sine wave inverter, and 40ah battery.

The bottom line for me is:
Just something that will carry TV for few hours if the need arises without affecting the ability to power bulbs too. Any suggestions/modifications?

I suggest you maintain the setup for the lights since you can't join the 7ah battery with the 40ah battery.

The setup with the 40ah and 300w inverter will be separate and only for the TV. So you will need another 10amps solar charge controller. Consider getting a 100w panel instead of 80w to guarantee better charging.

With the 40ah battery, she should be able to watch TV for about 3hrs in the evening if the battery is fully charged before sunset.

You want two things that may be hard to get: 24/7 power supply and very cheap hardly go together. Try the 99k package, may just be what you need. Just know you always get what you pay for in renewable energy, if you pay too cheap you always get what you paid for in terms of it being unable to serve you properly. Just my two cents, as always let's wait for the experts

Lol

99K? I am sure I can DIY for about half the price and achieve same.

Thanks for this section...v been introduced to inverter/alternate power generation. I recently installed bluegate 3.5kva/24v, 2 220ah luminous batteries. Though I had some issues initially, but it has been sorted out through people and informations gotten from this forum. Solenergy, Earthrealm and others,Thanks very much. May una wealth of knowledge never run dry

I have been eyeing this lithium thing for a while now and with these recent reviews, my mind is 80% made up to go for it. I just have to do a little more research to get all the answers I need. I might start with a small pack though, say 60ah.

I noticed there is lithium -ion and lifePo4 and some other lithium batteries. I read lithium-ion is the one with the tendency to catch fire, so going for LifePo4 is a safer option. Correct me if I am wrong @Caesar, simydan and other gurus here.
In practice, how far can you really discharge this type of battery? 50%?, 80%?

,, every battery has the tendency to catch fire when u dont follow due process

My inexpensive is not synonymous with very cheap. I simply mean reasonable, not on the high side. Especially if I go the DIY way. Example, sunking has an offering for 3 bulbs for 38k. I'll achieve same for far less. Thanks still.

This actually looks interesting, one just need to put a 300w panel and that's it. Have you used this? Because I have some questions:

1. It's rated 24v/250w considering that one has to use say 300w panel (putting loss into consideration), what happens since the Voc will be more than 24v and power may be occasionally more than 250w

2. What's the depth of your borehole? as this seem to be rated for 50m max (it's not clear if cable can go more than 16m with not issues).

Regards

naah, hvnt used it, am eye balling it.
i wouldnt recommend connecting a single 300w panel to it. even if it is canadian solar panel, it will struggle to keep up.
i wish i can see an mppt cc where the load side will handle upto 250w dc load.

50m borehole depth is ok for me, as most boreholes there are 100 to 120ft deep.
the cable lenght being 15m is not relevant to me, as i plan to buy 16mm dual core and join to it

@24v, i believe is the standard rating , it should work ok from 20v to 40v..being the voltage range of a 24v panel, even at that, the Vworking voltage of any 24v panel is about 18v to 22v.

i have a novel idea..to run the power to the sumo from the mppt cc input, ie where i terminated the output from 2 x 24v 250w panels.....wonder if anyone has tried this approach before
so when the sumo is working..it will pick the needed 250w it needs ffirst from the panels, while the excess would go into the cc, and charge the normal setup i have

This novel idea appears to be like you trying to run a variable surge load off the CC input terminals.

This is strongly discouraged - how will the MPPT find a maximum power point where there is an untracked source of drain in the system?

You must heavily oversize the panels or set the load to come on only at a certain voltage or whenever PV power exceeds the load demands else bad things could happen.

You need to be sure that the output bore diameter of the pump is the same as the pipe bore diameter in your current set-up so that swapping will be stress free.

Finally.
Nice one though.
Does this have the option to also work with AC via AC-DC adaptor?

And what are the specs nau? Wattage, volume, motor speed, torque, accessories, etc.

Haba, just try to dey add the technical specifications of these like this along with the advert. That way people will know what to expect rather than purchasing it and then finding out reasons not to buy it in the first place.

I was just thinking, what happens when mains comes on and supplies charge to battery while the pv also does supplies charge. Could there be a conflict atimes.? I have always been totally off-grid and was wondering as i have some installations soon.i will soon do some major upgrades.@ ceaser,niyioluyomade,mftcot and etal.

justcallmenuel:

No sir, it can’t work with AC, just DC only. And it’s 200w sir.

What he is asking is whether we can use an AC 220v to 12vDC adapter to power it.
Does it have a DC input port or does it come with only a direct wire from inside the appliance with battery clips?

Kindly show us the power input port if you don't mind.

There should be no issues with that unless the charge limit of your battery is reached. If utility is doing 20A and your solar is doing 10A it simply means 30A is going into your battery. So you need to be sure that your battery can accept the charge rate or you modify max charge as you find applicable(if you have that option on your gear).
You need to be sure that your chargers are intelligent enough to stop charging once battery is full.

hmmm, would you be kind enough to provide data backing your claims, about bad things that could happen. we are all here to learn.
lemme elaborate more on my plan,
there is an existing 12v 850va inverter, with a single 12v 200ah quanta battery and 2 x 250w 24v panels, hooked up to a fangpusun 50aD 12/24v 100v mppt CC. I intend to increase the total panel count to 1000w, ie additional 2 x 250w panels, in 2s2p connection, and then set the CC to limit charging current to 30amps, so the 24v 250w sumo pump, will be picking its power from the cc input terminal.....the overhead will hv a flow regulator to cut off and initiate flow when water levels are low, my other concern is how to programme the sumo to only come on in bright sunlight or during the hours of 10am to 3pm, since i want the whole setup to be autonomous,
i know its not being done here b4, my only fear is the possible heat that could be generated at the CC terminal by the 250w sumo load

@ceaser...the borehole is yet to be drilled, am just gathering data/planning, so am open to suggestions/ideas/improvements to my proposed plans etc
