Dont go from 4KVA to 5KVA, it is not worth the effort, time and money.
Since your current 4KVA does not meet your needs, go for 7- 8KVA Hybrid, with future Power demands in Mind.
if you Upgrade from 4KVA to 5KVA now, you will be doing another Upgrade, which is costly, very soon.

My ten Cents and l am not selling anything to you or anyone.

Can i get a hybrid 7.5kva to run 4x220ah batteries instead then with 9x350watts panels and please who can give good and durable hybrid inverter brands to work well with my luminous batteries?

Valto:
your 4pcs 220ah tubular batteries might not be enough to efficiently run a 7.5kw inverter, u need atleast 8pcs. 4 or 5kw hybrid inverter is your best bet for now.

alstacs:


Kindly shed more light on this.
Even if the 4 batteries, at present, are sufficient to power his load load for over 24 hours? And the size of the inverter is to accommodate future expansion of the battery bank?

gadgetplanetng:
Interested in the reason too

His load is less than 1000w

Bolatitodavies:
Yes my load less than 1000w, why i asked was cuz i feel my technician wants to charge high for 5kva when the money is sufficient to buy 7.5kva. Is there any 5kva hybrid that costs 500k+?

Valto:
if his load is truly 1000w, why suggest 7.5kw inverter for him, isnt that an overkill? he simply need a 5kva 48v inverter. your technician must not buy everything for you, u can buy things by yourself. u can get ANERN 48V 100A mppt, sorotec 48V 80A mppt, EPEVER 48V 80A mppt all at less than 400K.

I have luminous 4kva inverter already with 80amp felicity mppt charge controller with 4x220ah and 9x350watts solar panels, so my new technician is advising i switch to hybrid 5kva adding 180k extra to my 4kva inverter nd mppt charger which i feel im being robbed. Insead, i feel with 180k extra, i can get hybrid 7.5kva instead or is he offering me a good deal?

Valto:
it is not a good deal, unless he is giving you a growatts ES model. but which brand of 5kva is he planning to give u?

Bolatitodavies:
Plz can i chat you up on whatsapp? Abeg b4 they send me go village, i dont know the model hes willing to give me oooo but he stood on 5kva for 500k+

I don't think you are going about this optimally. I scanned through your message and I still did not find why you are upgrading. Why do you need a 7.5kva inverter?

You said something about planning for future expansion. If that is your only reason then it's the wrong way to plan. Solar is not about throwing money about but rather making every money you spend count. Efficiency is key in any system.

Rather than just buying the highest rated solar components you are better off first identify your load. The character of your load in term of timing and load type.

Typically the type of inductive load like water pump, freezer and non inverter AC and Fridge are things that determine size of your inverter. Plus the number of appliances you run concurrently. Once you have this figures then you size your inverter appropriately.

One thing you should note though. The load you are placing on your offgrid setup must be one you can generate back to the system either via solar or via generator / NEPA. If you take more than you can give back to the system, your setup would not last as you would over use your battery and kill it before you get economic value from it.

The first thing to consider is your generating capacity. Solar or NEPA (case in point I once lived in a place where 20 hours light a day was guaranteed that factored into my setup)

When you have your generating capacity, you then optimize your load to use below that capacity such that your battery can get daily full charge.

Next is your battery it should be able to take your night load and be at about 50% dod by morning

(Presuming you can take it back to 100% soc by noon)

Then your inverter should be sized to be able to operate at about 30% capacity when you turn your load. Over sizing inverter besides being a waste would also put a heavy idle load on your battery.

Solar has a good second hand market, if your needs radically increases you can also sell and upgrade. (Happens here all the time)

Best way to plan for the future is ensure your installation panel like where you installed your inverter or cc has enough space to do a drop in replacement for a bigger inverter without much rewiring.

Good morning everyone. I don’t know what to say actually because i am speechless, angry and unhappy
Got these so called two (2) brand new AGM batteries in December (100ah each) 1kva psw inverter and two (2) Of fairly used 180wats solar panels connected in parallel. The batteries have been giving me the value for my money... with just 1 led tv of 75wats in which i still often activated the power saving energy on the tv and also reduced the contrast and brightness of the tv to 5% which made the tv backlight so deem just in the effort to save energy. Also I have 5 led bulbs of 5 wats each with just 2 constantly on and the other 3 on at intervals and off almost immediately after usage. I also have a 12v dc standing fan which I normally turn on at lowest power speed just to save more power.

Amidst all these my strategies of minimizing power usage. What I just get from my 200ah battery in total is 5hrs on a full charge. I.e 12v dc fan at lowest speed, two 5wats bulb constantly on and the other 3 5watts bulb on at interval ( total interval bulb-on time do not exceed 45mins within the 5 hrs being supplied by the batteries. And 75 watts led tv( with energy server on and both brightness, contrast and backlight reduced to 5%

Does your batteries get to float daily? What are your charging parameters?

Michaelondon53:
yes batteries reads 14.3 , 14.4 daily sir (I.e whenever I use the solar panels and 13.9V when I use nepa.
Sometimes I use the two simultaneously, to quickly get full charge whenever there is nepa
Charging parameters : solar panels alone when there is no light. And both simultaneously (solar and nepa ) when there is nepa light

blockgeek69:
I recently installed a solar inverter system with the following setup:

1. 4 solar panels (each 300watt) = total 1200watt
2. 24v inverter system
3. 2 units of 230amp battery
4. 60amp PWM charge controller

My load at max capacity is 500 watt and could go as low as 300watt during midnight hours.

But I noticed that my battery charge depletes faster than its charging, is it supposed to be so? What i mean is, my battery could be 26v after fully charged with no load, but after 4 hours of use, it falls down to 24.5v even when the solar panel is still charging the system.

So I am beginning to wonder if this is normal or there is a problem with my system configuration or the charge controller itself since i am using a PWM cc.

Please gurus in the house, i need your input.
