chris81964: 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 . ![]() 1 Like

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 |

chimaaba22: 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 ! 4 Likes 1 Share |

Barezzi: 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. 1 Like |

Dam5reey: 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) 1 Like |

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 ) Nice technical atricle here - https://www.victronenergy.com/blog/2015/03/30/batteries-lithium-ion-vs-agm/ a very interesting video series here - https://www.youtube.com/watch?v=Ij7sIUMGRNo Item Pack Capacity [Ah] Model Name Model Variant [max kWh] / [recommended daily cycling kWh] SRP Excl VAT [USD] Trade Price Excl VAT [USD] 1 100 Freedom Lite Home 5/4 $ 3 399 $ 2 923 2 200 Freedom Lite Home 10/7 $ 5 674 $ 4 880 3 300 Freedom Lite Home 15/11 $ 8 252 $ 7 097 4 400 Freedom Lite Home 20/14 $ 10 598 $ 9 115 5 600 Freedom Lite Home 30/21 $ 15 290 $ 13 149 6 800 Freedom Lite Business 40/28 $ 19 923 $ 17 134 7 1200 Freedom Lite Business 60/42 $ 29 424 $ 25 305 8 1600 Freedom Lite Business 80/56 $ 38 631 $ 33 222 2 Likes |
