Hi Darryl, When looking at off-grid systems, in your opinion, how often is there excess current, i.e. more amps from the PV / Charge Source than can be absorbed approximately what percentage of capacity? Looking at Lithium Ion, like NMC, you can recharge at 2x Capacity (so 1/2 hour

Re: [RE-wrenches] 24 volt Battery Bank comparison

Hi Ray, Just a quick chime in on your series string comment. If you hook up 4 x 12V monoblocks for a small 48VDC system and begin charging at 58.8V, total voltage will be 58.8V very quickly but individual battery voltage will not be 14.7V. Battery voltage will have a large range from 14 to

Re: [RE-wrenches] Depth of discharge

Evening all, A quick note on DOD. Batteries / cells are often rated at voltages above and below 1.75VPC (1.7 - 1.85 are common), so ratings should be verified with the supplier / model. However, as anyone that has ever run a discharge test knows, the time / available AH from 1.8 to 1.7VPC

Hi Todd, Tried to post earlier from my phone but don't think it went. Dry charge (not moist but true dry) can be stored for 5+ years easily. The lower the humidity the better as the negatives will discharge in the presence of air if they become wet. One helpful option is to use cling

Hi Dana, Sorry for the delay - been on the road. Not sure if this has already been presented / discussed. The old standby from industrial chargers, is 100% SOC is reached when charge current drops to 2% of capacity (normaly based on 6 or 8 hr rate). Please note, this comes from an era of

Re: [RE-wrenches] discharging Rolls batteries

Hi Hugh, You are correct, my comments may have been too simplistic. However, one other key point we are missing is discharge rate. Note your comment, 400AH battery discharged at 10a for 16 (or 20) hours = 50% DOD, which is probably not the case. Use our S-530, which is 400AH @ the 20hr

Re: [RE-wrenches] discharging Rolls batteries

Hi Hugh, Based on your earlier number - regardless of temp effects - you were only removing ~25% of capacity. You will need to lower your low voltage cut off to improve performance. Remember, as batteries cool actual capacity is reduced, so if 200AH is 50% @ 25C it is significantly more
