Boss. I already have a borehole with submersible pump. I have some questions. How can I deploy a solar powered pump ? Can existing pump be used or a new one will be needed ? How much will.it cost just to power submersible pump and another pump to take Water from a ground level tank to the tanks on a tower ? Simple system with low maintenance. Thanks |

mavverick:It is best to change the pump to a solar/DC pump for a long term solution. The other option is to user a solar aRray coupled with an inverter system, but it won't last as long as a solar pump would. We can help you with that if you want. |

geesampower: Thanks for the reply, what I would like to know is the cost implication of going DC based pump. Can you state this please ? Thanks. |

mavverick:We are looking at about 450k-500k for a project like this. The pump costs about 250k-260k. Really I prefer using a solar pump to using an inverter coupled with solar power to run an AC pump |

@geesampower Is there any small Solar pump to pump water from an underground reservoir/well to an overhead tank? I am thinking of deploying a small DC pump for this purpose to be used only during sunshine. Please advise. Thanks in advance |
Re: Solar Power & Boreholes Jobs (FULL Pictures) Ask ANY questions NO SECRETS by geesampower(m): 10:15pm On Nov 05, 2015 |
donmajor2:Absolutely. And it can use just 200watts, but would only deliver about 500 to 1000 liter in an hour. If you are on wattsapp, you can contact me I can send the pump to you. |

Sir Pls is it that 2.7-3.3 rated generator CANNOT charge a 3.5kva inverter system or its just going to be slow? |

Re: Solar Power & Boreholes Jobs (FULL Pictures) Ask ANY questions NO SECRETS by geesampower(m): 8:19pm On Nov 13, 2015 |
peaceland:A very good question sir The rate of charge has NOTHING to do with a generators capacity, it has every thing to do with the charger either the inbuilt charger (inverter) or an auxiliary charger or the use of both. A typical 3.5kva inverter may not have a charger that is more than 20 to 30 amps, typically 24v, during the first stage of charging the charger uses a higher voltage to charge 28v -32v. This means the peak draw from your generator is 30amps by 32v which is 960va, so far you generator can provide this then you are ok. Does not matter if it is a 3kva generator or 100kva generator, your charger would only draw what is needed to charge the batteries and go through the whole 4 stage of charging. Real average draw would be more of 480va With a 20amp charger, charging 4 200ah batteries would take about 10 hours. For faster charging, add an auxiliary charger and you can half the charge time but double the power requirement. |

I have a 4300VA magnum inverter that has a charging current of 55Adc. i have a 6500VA generator. When ever i use the generator to charge my battery bank, the inverter draws about 12Aac, while feeding 55Adc to the battery bank(Bulk charging stage). The house draws an extra 4Aac, bringing total draw to about 16Aac. My generator usually groans like it wants to die ![]() ![]() ![]() ![]() So check your maths again... |
Re: Solar Power & Boreholes Jobs (FULL Pictures) Ask ANY questions NO SECRETS by geesampower(m): 4:31pm On Nov 15, 2015 |
Barezzi:There is nothing wrong with my maths. All inverters don't have the same charging current. What you need to do is to check the charging current of your inverter. You just said your inverter has a charging current of 55A dc, that is YOUR inverter. The example I gave above was 30A dc Max NOT 55ADC. So don't mix things up sir. The importance of my comment is in educating the reader on how to calculate this them selves. this is not a thread for one fits all, it is for education. You take the knowledge and adapt to your unique situation. If I say for every 4kva magnum inverter buy a 8kva generator. Does that mean I am making sense? Absolutely NO. Because you still have to calculate rate of charge. Would your inverter need 10hrs to charge 4 200ah batteries? Absolutely NO. But the example I gave above would need 10hrs to charge the batteries. So my maths is not wrong in anyway. Situations only differs You have to make sure you put round pegs in round holes. Buy a generator that can deliver what your charging current is And don't neglect the voltage too. The lesser you have to step down to the more current your generator can comfortably deliver. 1 Like |

geesampower:Mr barezzi, pls note what I said; THE RATE. The question he was asking on is if one generator would charge faster than another generator. RATE has NOTHING to do with generator size but EVERYTHING to do with the inbuilt charger or auxiliary charger you are using. Thee generator size only determines IF that power can be supplied or not. Appreciate your contribution. Can you share with use the other appliances you use with the generator sir |

Nice one, my only grouse is the 10 solar hrs. Its not realistic. 5hrs is a better estimate. i am very interested in adding wind to my current setup. |

How do you calculate the optimal battery bank(AH) required to store say 8000wh generated by 4, 200w solar panels over 10 hours of sunlight ? Thanks for the enlightenment so far. |
