Re: [RE-wrenches] Aquion Batteries

I have used Simphiphy. Had a problem over time nearly 2 years the cells were what appears to be out of balance. I think i balanced them by setting the charge voltage higher than recomended. I think the factory has it wrong On Wed, Jan 23, 2019, 1:39 PM Dave Angelini Offgrid Solar < offgridso..

Re: [RE-wrenches] Aquion Batteries

Simplyphi does not have a built in method for Soc. The BMS works well but the install requires an energy monitor with a shunt. Too much work for me and my clients. Their batteries are too small at 3.5 kwh or so. If they changed the size up, and got Soc out to OUtback or Schneider I would use them.

Hi Tump, If you recall, this is EXACTLY what I was calling into question on this list back on November 11th, 2014 and again on Jan 29th, 2016. It looks like you have confirmed my suspicion. The battery can not possible provide the rated capacity. I hope others that have tested these batteries w

I have dual Sunny Islands & dual SB 4000TL22US w/ 20 stack on one and another site w/ the Aspen 48M w/ Schneider. I will say this; cost per amp hour of storage sucks w/ the Aquion batteries. Both my client and I feel, that the batteries, despite there size have very little capacity. The “30”%D

Drake, I just did my first Aquion Install on an off-grid second home. It is a 24V single VFX3524. 10 Aspen 24 volt stacks. No one has been living there since I installed it but at least the generator stopped running 2 or 3 times a day just to maintain the heating system. The generator hasn't

Re: [RE-wrenches] Aquion Batteries

We had a customer request them but once we found out how many it would take, he decided on the deka unigee instead. l dont like running my OB's at such a low voltage as they seem to get hotter due to the higher current. Some of our other product lines don't even reccomend aquions due to that low vo

Re: [RE-wrenches] Aquion Batteries

Hi folks. Tim Wood of Aquion asked me to post this on his behalf. Early versions of the Aquion battery had substantially lower continuous and peak power ratings.  Very few made their way out into the field however some did and we believe the concerns expressed on the board are related to those e

Re: [RE-wrenches] Aquion Batteries

That new chart is for a single block, but we would want the M100 or M110 which is 12 of those S30 blocks connected together (580 AH @ 20 hr rate). I haven't tried them, but I penciled out the ROI and at 3000 cycles they stand up well against other lead acid batteries. 40 v is low, but I believ

Re: [RE-wrenches] Aquion Batteries

Thanks Dana. The new curves don’t look much better. Look at the space between the curves and realize that they are only 2A load difference. If we extrapolate to 17 amps the capacity will be greatly reduced. They need to show what the voltage sag is under full 680 Watt load. Has anyone actually

Re: [RE-wrenches] Aquion Batteries

I second Larry's concerns about Aquion's SOC/voltage curves and tripping LVD at only 40% DOD with standard PV equipment, tied in with not being able to handle high discharge C-rates and surge loads. I did some math on running a typical off-grid home with a well pump on Aquions, and it wasn't pretty

Wrenches We were looking at these “Aquion batteries” but once we compared the power, voltage operating range and storage of the Unigy vs the Aquion we went with the Unigy brand the volt range worked normally no changes to the LBCO setings. I have Unigy applications going back close to 15 years with

I too am interested in anyone that has installed these. I had some concerns back on Nov 10, 2014. Here is a copy/past from that conversation: Something does not add up to me. The cell has a voltage discharge curve way outside that of RE equipment, 1.75 Vpc down to 0.5Vpc. I can't see how this t
