The Rosie / Re: Beta Firmware
Last post by FNG - October 29, 2025, 06:52:51 AMReleased 25.10.27.00
1- Changed Grid support to allow the voltage to go down to 47 (Used to stop at 48)
2- Changed the charging behavior on Rosie when no MPPT present or MPPT unlinked Rosie will only start a new bulk charge when Rebulk is hit or the AC IN is lost for 1HR or more to prevent back up systems from fully charging every evening

1- Fixes a quirk with logging that could on rare occasions cause the Rosie to reboot and thus shut power off for 1-5 seconds
2- Adds full support for closed loop
3- Increases the support for parallel Rosies for more than 2
4- General tweaks on operations

Hawke's Bay / Re: Beta Firmware release and ...
Last post by FNG - October 29, 2025, 06:44:13 AMIt has been a while since I updated this or the firmware, Darren has worked on MPPT code a lot lately and we released 25.10.17.00 best served with newer MNGP2 code of 25.10.12.00 or newer
1- Revamped MPPT tracking all around for improved tracking
2- Added ramp rates based on SOC or Voltage to slow the tracking when close to full on Lithium to prevent over shoot
3- Fixed SOC when received from the canbus
4- Fixed a few other quirks behind the curtains

The "Classic" charge controller / Re: Estimating power use from ...
Last post by JohnsIsland - October 28, 2025, 07:27:14 PMI am in Washington state. I wont go lithium this time because I live on a remote island without a fire department, and I would have to upgrade my victron AC chargers and victron inverter since I am not 48 volts.
I realize the danger of a fire from lithium batteries is remote and I suppose even FLA and AGM batteries present a fire risk.
I know my AH use will increase with time and lithium are thr future, so I will probably convert to lithium at some point in a few years, first by switching to 48v, then to lithium when the new batteries reach the end of there life.
Thanks,
Jeff

The "Classic" charge controller / Re: Estimating power use from ...
Last post by ClassicCrazy - October 27, 2025, 08:43:24 PMthe self discharge rate goes up on old lead acid. So kind of like filling a bucket with holes in it.
Why don't you get lithium ? These days you can get a 314 ah 48v battery ( around 16 or 17 kwh) for $2000 shipped price.
But maybe you are running 24v system ? There are some 24v lithium options out there . But upgrading to 48v really is the way to go these days.
maybe you aren't in usa ?
