Please house I urgently need your help. I need to buy a 24v pure sine wave inverter at most 1.5kva capacity. I am currently considering a BTS inverter which I saw on Konga and Jumia, please is that a good inverter? Which other one can you recommend. Thanks.

Mopower 1.5 or Sukam 1.6 (Falcon+)

purplekayc:
is this watt meter okay?

That is just fine. I use exact same meter and it works fine.

chris81964:

It holds 160 liters that is under pressure. The pump can be much smaller less than half hp. The pump kicks in at a predetermined level set by you. Yes you need 24/7 power and that is what we provide

I have finally settled on a better solution in case somebody is interested

http://us.grundfos.com/products/find-product/SCALA2.html

The solution to be implemented with tank has several problems in the long run

Personally after 8 years and 3 booster pumps , 2 tanks and 3 pressure controllers replacement I found the scala a pleasure to use. My wife does not allow me to switch it off !

Normal coventional solution has a tank that has a diphram which fails after cyclic use, also the pressure needs to be set after every year atleast ( like pumping tyre), the pressure switches loose the control after the spring has worn out or get clogged with borehole supply (. I tried even the german ones

The scala uses a variable frequency DC motor So consumes between 300 Watt ( 1 tap open) or 6000 watt ( 4 taps open)
No separate tank needed and unlike tank the pressure does not drop midway of the shower but remains same on any tap independent of the open taps as the flow rate is controlled not pressure . Also has tap left open, pipe leaking no water inflow protection preventing continuous running of pump draining the battery

Off course needs full time power but thats the reason we use PV and inverters . for me it consumes around 1.5 to 2.5 KWH in a day for house of 8 people including gardening and car washing and washing machine ( some data is missing as my computer is not always on to upload to PVoutput)

What's the technical specification of 45a-12/24/36/48v=70k & ANY discount pls.

Max PV input 150v/45a

Barezzi:

Chris,
Thanks for this, i personally hate overhead tank stands. They're really an eyesore on the skyline.
At 160 litres, the submersible pump will cycle several times per day/night. At such high cyclic use, your client might need 2 or 3 pumps on hot standby cos of potential high failure rate.

A holding GP tank will reduce that cycling. The oversimplified sketch below is how I'd implement it.

a subsurface tank could even be used inplace of the surface gp tank...making the whole system almost invicible

Good morning house, a neighbour of mine is planning of going completely solar and he asked for my help in acquiring the following components
A 3.5kva inverter
Two 200ah batteries
Two 300w solar panels
A 40ah pwm solar charge controller 12v/24v
He is planning to use it for his home and anytime there is a service for his church. My question can those panels charge his batteries to an appreciable level & is the charge controller okay or should I go for an mppt? Thanks

Completely off grid.. means more Panel.. sun is not smiling always..
MPPT controller.. 92% efficiency compared to 80% on PWM...
Battery size is 4800wh... Divide by 3hour of average sun recommend panel is 1600Watts...

How do you implement this in a borehole setup without a GP subsurface buffer tank?

This is mathematics,
we are talking reality. He would not only be charging the battery, he will be using during day time as well..

Oversizing panel is the solution for totally off grid systems..

Maybe u used arithmetics to arrive at your conclusion.

Hello, instead of arguing after asking a question, I advice you read/listen to pick valid points on an interactive forum like this... So many of us oversized our systems e.g George D did same and i myself in most of my installations just to be on safe side ! Pls you can always use mppt as we have inexpensive brands .. As some people see solar as being a bit expensive , most see it as an investment on the long run... Cheers !

How do you implement this in a borehole setup without a GP subsurface buffer tank?

The borehole pump does not need to be replaced ( if existing) it is always better to collect borehole water in a large tank after passing through a 20 or 10 micron filter - The settling allows the sediments to get reduced - the outlet of large tank ( typically 1000 -5000 ltr) will be directly connected through Booster to house . That way in remote cases of no power or failuers your client will atleast have flow of water to his taps
the large tank does not need to be elevated but kept near the house or borehole
That Way borehole pump is also not working with additional head. Incase a VFD bore hole pump is used ( in my case Grundfos MQ) it can run on as low as 100-150 watt

If time permits I will post the photos of my setup.

I cam across an interesting formula in Powerforum Africa ( SA) Almost everybody blindly follows it. they call it 5,4,3 ( 5 KVA inverter), 400 Ah battery and 3KW solar - This is on average perfect for a family of husband wife and two children ling offgrid using all modern appliences

What made it interesting is after detailed calculations and measuring power of all my house to last milliwatt I had come to same conclusion 5 years back - off ocurse given prices then the 3 KW tool 3 years to achieve ( LOL)

Lithium Batteries Group Buy

Aftyer searching over past few months and poring over data sheets I have finally settled on these bat-teries
http://www.freedomwon.co.za/home-battery

- Mainly because of their performance of 100 Amp ( perfect with 4 KW inverters) and BMS and DC mCB built in and compatibility with Victron inverters and proven performance in hot climate

The trade price list quoted to me are below ( higher than chinese batteries( PylonTech) but cheaper than European counterparts as as LG Resu /Samsung SDI )

Unfortunately the shipping is minimum 1m3 ( 900 USD to Nigeria)( atleast 7 -10 units)

So incase somebody is interested we can arrange a GROUP BUY - Personally I am interested in 10 /7 ( 48 V 10 KWH ) battery - Currently I use a 400 AH 48 V so 50 % DOD makes it equal to 10 KWH battery only - Replacing the Lead Acid with Trojan Re200 will cost me 1.1 million while the 10/7 Li will cost 1.8 Million

For those of you who may only compare the prices to Lead acid please note that Lithium can be cy-cled to 70%-capacity daily for more than 3500 times - 10 years or 7000 Cycles at 50 % DOD

It is also more efficient in charging returning average 95 % against overall 80 % of lead acid. lead ac-id is also most inefficient between 80 % to 100 % SOC (more than 50 % is wasted in heat )

How much is this product? Need something similar. Been using some other setup - pumping machine & Pressure pump for long and it still not great the way i want.
