OTG

Hi. Ok thanks guys. I was thinking about 3 months as distant future. I feel a lot happier to proceed now.

Hi gents and mainly TTT and Plonkster. Have heard you loud and clear so what I did was replace the Axpert 3 Kva with a 5 Kva and purchased a Pylon US3000 Li-Iron Phosphate battery. This was the best I could afford. Due to the really low load it will be used on I only got one. What I am wondering now is if I want to add on in future will it be a problem. Near future or distant future! Will this be good or bad for such a battery. Any comments will be appreciated. Many thanks.

Ok guys thanks. I dont want to muck about so I think straight to Lithium straight off. Can you recommed a good value one for my 24v system and where to obtain. Thanks.

Hi. Yes. Pretty new at this.Can you recommend batteries

Hi Thanks 1/ No connection to DB. 2/ Yes as you assumed. 3/ BMV? Sorry not sure what that is.

Thanks TTT. I have an Axpert 3Kva 24V inverter. Input range 30-66Vdc and Max 75Vdc. Panels 4 x 280W. I have joined 1 & 2 in series as well as 3 & 4 and then joined in paralell. I want to place another 4 panels in similar way and have 2 x strings. The ISC is 9.45A and Max 8.92A. I will get losses and expected between 60 and 72 W readings from the panels. Inverter set to 30A for charging. I do have a combiner box with 15A fuses. Battery isolater with 2 x 100kA 24V fuses. I have 4 x 105ah lead acid batteries. I have noticed on charging that I already get 30A charging and was only expecting under 20A and its a bit concerning being at inverter MPPT max. I have set the inverter on SBU and have the ultility power come in at 24v on the batteries so as not to discharge them to much. Basicaly the batteries only come into use for a few hours at night but are not required for much pulling during the day. Am I on the right track here or endangering the setup. Thanks again.

Hi, my name is Paul and new to the forum. I have been moving over to solar but as it catches me more and more I am increasing my systems. At present I am fitting a second system and want to know if I can describe my design and get advice. Many thanks. Paul.
