The "Classic" charge controller / Re: FLA Charge current Setting...

Last post by ClassicCrazy - October 08, 2026, 10:23:35 AM

What happened to the FAQ section - I cannot locate these links any longer

Server crash, no way to rebuild, no more FAQ.
Web master started to port it over to be part of the web but it's not easy to navagate.
I don't even see a link to get to it so I guess FAQ is dead...

Darn ! You had written so many detailed directions in the past on the Knowledge Base , especially for the Classic . It would be sad if they are all lost. Some of them I probably copy and pasted in replies to people in the forums here,but often I just posted the link. I wonder if someone could get them from the Wayback machine, though that may only have been for websites. Maybe I will give it a try and report back if it works.

I verified that the  MNGP2 is healthy using a bench power supply. So I am sure Rosie is not supplying power to the Display.

I have an RMA number and will get the Rosie to Midnite in a day or so.

Hawke's Bay / Re: Why does charging stop in ...

Last post by Wizbandit - October 06, 2026, 11:38:38 AM

Might be firmware, don't use BETA, the only stable version is 26.1.14 right now.
We are working on a few bugs and testing new firmware right now.
Progress is slow...
Update Firmware, "Set System to Defaults" (USER BUTTON, system functions)
Power-cycle

Not much to go on when you don't have the details of your battery voltage and charge setpoints .
What is the soc of your batteries when you say it needs a good charge ?
The battery voltage of lithiums hold very steady for much of it's capacity .
Need more info. I don't remember if you set it up closed or open loop ?
If closed loop you are letting the bms dicatate the charging.
Do you have software that let you see what the bms is doing , what it's setpoints are, and each individual cell voltage ? Or if what the status of the bms ? Cell differential , if it is in overvolt protection for a cell , and maybe balancing ?
I had recommended you get a different kind of battery with bms that you could use their software to change bms setpoints, and monitor every cell , and status . If you can't do that with your Ecoworthy then you have to do some guessing as to what is going on with what the bms is doing since it controls some charging even if you are open loop. 
It may not have anything to do with your hawkes bay controller that you are seeing what you are.
Oh , I see in your title of post that you say the soc is 87% . Is that from Whizbang, or from bms reporting ? 
If from Whizbang how did you calibrate it for 100% full ?
If from bms soc reporting , those can get way off and shouldn't always be trusted.

It's open loop. The battery state of charge was 80%, so plenty of room for energy to go. One minute I was watching 61A going into the batteries, and then went out ten minutes later and current was at 0A. Batteries still report 80% SOC.

I have the JBD software that came with the Eco worthy batteries. I haven't poke around with it yet, no need for fingers to get into something I have yet to totally figure out.

Install the ecoworthy phone app it should show exactly what all your individual battery cells are doing via Bluetooth. You cant trust the battery bms soc guesstimate. Need a reference shunt to keep accurate track of soc.

No.
I don't think the mngp2 has power long enough for that to start up.

I disconnected the whizbang and measured the voltage on the 1-wire.
It to is alive  for only the same period . 7V or so.

does the mngp2 show up in the updater app ?
That would mean the bluetooth is still running.

I did use a multimeter (Fluke 115) to capture the max/min on startup. I had to do it twice as the captured "Min" is whatever the capacitors were. The second time they were precharged and the drop was mV.
I measured inside the inverter - after the E-Panel connections.

All the connections were tight (pulling on it). I will re-torque since I have it open.

Did you check all your cable connections to breakers and anywhere else ?
Look for loose crimps in ring terminals ,etc.
I would use meter and check the voltage at various points and also at the terminals on the Rosie to rule out voltage drop as it starts up.
Go to Midnite and start a repair ticket - the techs will know what else you should try before you disconnect everything .
I don't have a big rosie so can't make any other suggestions.

The Rosie / Rosie is dead.

Last post by HIT99 - October 04, 2026, 12:11:20 PM

My Rosie died early yesterday evening.
No LED. No MNGP2.
I didn't measure anything too hot with an IR thermometer but it had time to cool down.

No significant load. A microwave was used (1200watt) before the event and I think the cycle completed.

No battery alarms.
MPPT recorded a low around 53V.

Tried restarting by cycling the inverter battery breaker.
Inverter off (FP switch). No ac loads connected.
Solar assistant disconnected.

The fan comes on momentarily . LED blinks. MNGP2 backlight and then goes dead.

Offgrid
Installed: May 2024
Rosie MNGP2 fw:  25.x.x ( I forget the exact )
Solar Assistant:

Charge controller: Victron MPPT
Battery: RUiXU 600ah approx 88% 53.5V. CAN connected to Victron and not

I can't remember what I have for LBCO etc but it is a lot lower than that.

Any tips for diagnosing before I rip it off the wall?

- corrupt FW? Factory Reset jumper?
