GODAKPAN:
MINE COST A LITTLE ABOVE 900K, 3.5KVA INVERTER, 4 BATTERIES, 8 SOLAR PANEL AND CHARGE CONTROLLER, ITS BEEN WONDERFUL.

COST: PANEL =48K EACH
INVERTER =135K
BATTERIES =56K EACH
CHARGE CONTROLLER =50K
BATTERY/PANEL RACK =40K
INSTALLATION =75K

Benbisco:


This your "specs" is exactly like mine but we just noticed that it goes off in the middle of the night and we are left in the dark till the sun comes up on the morning.

We had a good time with the 1.5kva and 2 batteries without panels for 4yrs and decided to step up to 3.5kva last December to accommodate the refrigerator but it has just been falling our hand since this week.

Have you ever experienced such?

Proudlyngwa:


You messed up stepping up without a professional advice.
How many batteries do you now use

Benbisco:


Four brand new batteries, 8 panels, + charge controller. A company was invited for the installation.

Proudlyngwa:


What is the Ah rating of each battery ,then give me the total.

Companies do mess up.

Benbisco:


200AH 12V, X 4; 800AH.

Proudlyngwa:

800 x 12 = 9600 wH

Divide 9600 by your 3000 watts (3kva) inverter, you will know how many hours it will last.

If your inverter does not adjust power generated based on load automatically, you will have a lot of power wastage and loss of battery efficiency.

DMerciful:
The fact that the inverter is 3000w doesn't mean it consumes 3000w. It consumes the sum of the loads connected to it plus the inverter self consumption which is usually around 120w for 3.5kva. Reduce ur loads and use energy saving devices. You can state the loads on the inverter and their wattage so I can help

fedorahat:


Not all inverters are intelligent

DMerciful:
Has nothing to do with intelligence. The most basic inverter does this even locally made. It's physics, if a system is 90% efficient means output=0.9input

fedorahat:

Efficiency is 0.8 of total power, and it is not advised to load your inverter beyond 60% of its capacity, actually we have inverters that need load sensing to cut off otherwise it generates battery waste.

DMerciful:
Efficiency is different from % loading. Loading around 60% is go give a factor of safety to ensure longevity

fedorahat:


I never said efficiency and %loading were the same thing, I was trying to give an advise to help the battery life the system.

Here I come

If you are building your house consider renewable source of energy.
I'm talking about solar energy,segment your solar panel into 2.One segment (4 200W solar panels) to power your house during the day,the second part (4 200W solar panels ) to charge your batteries. Get a solar dc pump for water supply,it starts pumping whenever the solar panels receive enough energy from the sun.
Mind you, it is not advisable to use your inverter to with pressing iron. Alternatively you can use 'Dice current booster+optolator' to reduce the effect on the batteries.



Getting a good batteries is the main reason you will need to involve expert in the field.If you mistakenly buy fake batteries,you will cry for wasting your money.

The best batteries in the world are lithium-ion batteries which are VERY expensive.

DMerciful:
I bought the batteries zenith 200AH x 4 @ 52k each. The inverter is 40k then, maybe 50k now cos of dollar . The rack was about 15k. It is good to install with a stabilizer for protection.I use 5KVA stabilizer although I have it before....all in all about N273k

dragnet:

the stabilizer was for input to the inverter or output from inverter?

DMerciful:
It is placed before the inverter to protect it and ensure stable voltage for charging.
