Regarding GSJ =ere is what's been achieved. -all Aquion battery =odules are wired to bypass the corroded, water damaged circuit boards =hat could interfere with charging profiles. -sunny islands (6) =ere downgraded to firmware version 6.0.02. This was done to allow a =roader, linear charge profile to be set -charging parameters =re now based on voltage set points rather than state of charge =alculations done internally with different references. -max charge voltage =as been set to 58.5V and the batteries will not stop charging untill a =oltage 1.5V over the set limit is a achieved for 15 seconds. This gives =hem the ability to serpase the previous charge voltage of 56.7V - the main issue =hat caused so much down time before was as follows. A target charge =oltage that matched the Aquion batteries was not possible with the =revious profile. Compiled on that was faulty Aquion circuit boards =reventing the batteries from properly charging to a suitable voltage. =quion, as we know, is no more, so it's impossible to obtain =eplacement parts. Aquions bms never met the as advertised performance =nd created more issues than we could have imagined. In short, the =hanged I made allowed for a higher, more suitable battery voltage to be =chieved and prevents the premature shut down we saw before. Again, sorry for the =elay, hope all is well Thanks 4 EFTA_R1_01835454 EFTA02624725  Dan Chrisman Senior Technical =pecialist Prosolar=LLC From: Richard Kahn Sent: =/b>Wednesday, July 11, 2018 10:30 AM To: =fipBrian Prosolar : Brice Gordon u j : Re: rnaay June can we do thursday morning or anytime friday when can expect tan's summary? please =dvise thank =ou Richard Kahn HBRK =ssociates Inc. wrote: MMI On Jul =0, 2018, at 2:18 PM, Brian Prosolar Afternoon =ichard, EFTA_R1_01835455 EFTA02624726  Brad is traveling to =an Francisco for a conference and I'm boarding a plane to STK. ='ve asked Dan to write a synopsis of his efforts and we have =een monitoring for proper function.
