Good morning ,I did a search but couldn't find anything on resetting lifetime ah + and lifetime ah - I'm thinking it's not supposed to be reset kinda like a odometer on a car ,, I wanted to do this as I recently did some upgrades on batteries and panels ,, and figured I would try and reset it today as it's the last day of the year .
Thanks
Don
Merry 2024 !
There is a modbus register, at modbus address 4353 that I think will clear these values from non-volatile memory.
First, you need to get into the modbus editor in the TWEAKS menu.
I was hoping that I could find a good explanation on this forum on how to do that but evidently the search function cannot find it.
But basically, in TWEAKS, go up to the top menu and then hold down the left arrow key and press the upper-right soft key. I think it is up two menus from that ?
Anyhow, press UP until you get to the address 4353 and then go to the right and change the value.
The value of 4 should make it erase the LIFETIME AMP-HOURS
5 should clear WhizBang Junior net amp-hours
This is where I start to get confuses... The code says that 4 is lifetime amp-hours but it might be a bit higher number. I would just slowly go from 0 to 8
THEN I see that CLear All is going to number 37 ! So that is probably it.
You should not have to press enter or anything else. I thought I would have made it harder than this.
Lettuce know if this works. Maybe someone will correct me on anything wrong I have said about getting into the editor.

Instruction to get to the Modbus register editor:

I've tried to reset lifetime and wizbang junior kWh and amp hours ,following instructions ,but it didn't reset to zero ,( I did this while the classic was not producing power just powered on ) I tried each value from 0-8 and 37 in modbus address 4353 in the modbus editor. Tried with pressing left soft key and enter ( as hockey posted )and without using left soft key and enter as (Bob posted ) ,I even powered down the classic and rebooted after saving value of 37 but it didn't reset , once powered up went back into the modbus editor and I noticed the value changed back to 0 on modbus register 4353 . I'm running software mngp 2197 and 2245 for classic if that makes a difference.
Thanks
Update ! No need to go into modbus editor , just go to main menu select logs press enter twice use up or down arrow to select what you want to reset press enter then select yes or no by pressing left or right soft key .
Thanks
