  1. In that case a lithium battery would be the better choice since it costs around the same.
  2. How much does a 12v200Ah Trojan cost ?
  3. Show me one Lead Acid battery that can provide even 800 cycles at 75% DoD EDIT: Ok my info is a little inaccurate, see attached for a more accurate ref.
  4. I've been buying DC GEL batteries ( 12v200Ah ) for around R3.2k , and the ones im using are safe to discharge up to 75% of capacity. 400 cycles at 75%DoD .
  5. I'm using a Sako 3kw low frequency inverter, 3 years and counting.
  6. HI wtjaden, Appreciate your recommendation on the charger. I'll surely look into buying this if no one else can recommend anything better. I purchased the batteries from an importer in Pretoria. Purchased for R5.5k each 12v100Ah
  7. Hey guys, I purchased 4 x 100Ah Lithium batteries about a year ago, and since then I stopped having weekly power cuts. So I purchased them for nothing, as the 4 x 100Ah DC Gel batteries are working just fine. I would end up using the Lithium's at some point ( going off the grid on one phase when electricity prices start getting more steep), so for now I need to know where I can give my batteries a boost charge OR maybe I can just buy one. Can someone please kindly point me in the right direction. TIA !

    LFP / LiFePO4

    Im also interested in buying a few. Where you ordering yours from Mike, and do you have a spec sheet ?
  9. Nicely done ! did you DIY or had some company do the install ?

    So this Lithium battery is taking the battery market by storm. But is It really that good compared to Lead Acid ? I have been buying Lead Acid batteries that offer 400 cycles at 100% DoD.
  11. Thanks for the information Wetkit. I decided to buy a new 5kw Hybrid inverter. The only problem with this specific inverter is that it can only operate in Hybrid mode ( meaning auto switching between PV-DC-Grid) is if I have the controller built-in . The controller is not a MPPT controller but PWM. Now I have heard that MPPT is far better than PWM , but now in this case would it be a train smash if I end up with a PWM ?
  12. Hi Wetkit, I actually don't mind it right now where the Solar charges only when City power is cut off. My UPS is a 48VDC system. So how I connect this. I have the Solar panel wired to the controller, and then wired to the batteries ? Also the battery maximum charge current is 30A , so would this mean I need a 30A controller or can I buy a bigger one ? Thanks again for the input/advice.
  13. Thanks Cint for the information. I wonder if anyone has done this before ... hmmm ...
  14. Can anyone tell me if this is possible and if yes, how do I go about ? I have a UPS that has a built in 15A charger. Now if my UPS shuts off due to low battery voltage, it would be great if I can get Solar to charge the batteries while AC is out. The question is can this be done ? Meaning, obviously when AC power is online , that would mean the UPS charging the batteries together with the Solar. My concern is overcharging of batteries. Any input is appreciated.
  15. Actually you do get 3 phases with 3 different meters. And you also right with 3 phases having one meter.
