  1. Good day, My off grid setup is 2 x 330w solar panels 60amp pwm charge controller 1 x 205ah valve regulated lead acid gel deep cycle battery. Solar tracking mount My question is the charge controller only has a float setting which is HVD High voltage disconnect which you can set between 13 to 15v The battery specs are for floating charge set to 13 6 to 13 7v For Cycle use set 14.6 to 15v What would be the best setting to use? As the controller refers to this as float setting should i set the HVD to 14 6v as per battery instructions for cycle use o
  2. Can you please give more details
  3. Would these maybe work? https://talontools.co.za/2-pole-alternators/
  4. Thank you for all the info.. I will set up a basic solar system 2 x 400 watt solar panels a 5kv inverter and 2 x 12v 105 ah and charge controller to have some power on the property.. i will then experiment and play around with the water turbine and hopefully i can get something decent out of it and add it to the existing system.
  5. That is a awesome idea.. however my river flows so im looking at harnessing the power... Im looking at two bicycle rims 1.5 neters apart with stainless steel blades.. This should give mr loads of torque.. Lets say i get 50rpm from the turbine i can gear up 4.1 three times so 50 x 4 x 4 x 4 thats 3200rpm
  6. I am looking at one that will run on the water.. still need to calculate the flow rate.. but its fast flowing water.. im also looking at width about a meter or meter and a half.. i should get a decent rpm and enough torque to pull a cow lol hopefully.
  7. Thank you for the advise. Ok so maybe i need to look at a car alternator i have seen some that are 24v @ 110a thats 2640 watts. I can gear up to get a higher rpm but what is the minimum rpm that the alternator will produce that power.
  8. Thank you will contact them.. I have seen some of these systems and the cost is crazy.. and support and on site help more money... But for sure maybe they can advise... So far seams i must do this myself.. very little advise help on diy projects everyone wants money.. If a wind turbine using a treadmill motor can be sufficient at random rpm and no wind at all.. I am sure my water turbine running 24/7 using same concept can do better.
  9. I am not sure of the current at this stage, hence i am doing research.. My water turbine is based on a wind turbine as there is not much info in SA on water turbines.. Using a tredmill motor this is what the minimum rrquirements are. Mnimum Volts to RPM ratio of 0.035 Minimum amperage rating of 5amp Min 100v @2500 rpm Will output around 14.4v at 450 rpm Obviously this is going on the 100v @2500rpm giving 14.4v at 450rpm minimum. If i can get higher voltage amperage motor at not to high rpm it will be easier to obtain the right volts at maybe lower rpm or
  10. Thank you for the info, much appriciated. I am looking at getting around 14 to 24v from the turbine.
  11. Yes 24/7 fast flowing private riverfront
  12. Good afternoon.. To all the electricians and solar fundies out there, I need some advise, help with a diy off the grid power project for our home I am planning to build an off the grid electrical system using a home made water turbine which will be running on a river using a treadmill motor as a generator / alternator and up gearing to achieve the rpm needed to output anything from 12 to 24 volts DC. From this it will go to a charge controller and charge the battery bank of say 2 x 12v 105 ah deep cycle battries.. I want to then run a 5kva pure sine wave inverter to supply us
  13. Thank you so much for your advise and ideas.. much appriciated and will defiantly look at them
