Hi, Had this fault pop up on my app this morning - F55 - DC_VoltHigh_Fault Looking at battery voltage it had shot up to 62.6V - Inverter is connected to SEPLOS Mason LF280K - BMS Over Voltage Protection is set at 56.80 - connected via CAN The alarm has now cleared - anyone else had...

I was looking at the custom view on Sunsynk Connect app as below. Only showing the Battery Voltage, SOC & BMS Voltage. Is there an explanation for the discrepancy between the BMS voltage & the Battery Voltage? Is this a natural variation taking battery temp & compression into account.? Or is...

Thanks for the feedback. I will try to understand these more to expand my knowledge.

I will look into these values & understand their exact meaning & then move forward. Only been on this journey since March, so a very steep learning curve. Thanks

HI, Are there any issues glaring out regarding the BMS settings? Thanks

Hi, Just to add my experience. I had a distance of approx. 30m to cover & was looking at a similar solution. I did have a cat 5e cable spare running from the house to the shed. I wired up the CT & it is responding fine. In all a total cable distance of 35m Sunsynk 5kW with 15 Jinko 420W...

These are the settings from my BMS. Not sure if I want BMS or inverter to control battery pack at the minute. The NEEY is already set as stated. Thanks

Sorry, you mean set my BMS overprotection to 56v. I will check what it is when I get back home. I thnk I did change the over voltage protection, but will double check, when back at home in the morning. Thanks for your time

yes it is via Canbus

Currently my Float V & Absorption are set to 56.7v on Inverter Equalisation the same (is this a requirement for LifePO4) Looking at Sunsynck Connect my voltage at 95% SOC is at 53.5v, so cell voltage is low. When solar puts up to 100% SOC my voltage goes as high as 57.9 as below: So I will...

Simple, I live in the UK, we have no sun at the best of times :) The energy supplier we use has a low cost tariff in the morning hours, typically between midnight & 5am. The smart meter we use has 30 min time slots - this morning majority of the early slots were a minus per kW As you can see...

From what I have read its best not to hit max every time with these cells. Obviously I may be wrong :)

Hi, Just setup my system: 15 420w Jinko Solar Panels 5kW Sunsynk Hybrid inverter Seplos Mason 48V 14.3kWh battery with 16 Grade A V3 LF280K EV BMS setup advice thanks to @houseofancients Has been supplying house for 8 days , all looks to be running fine - using Octopus agile tariff & daily...

Ha Ha I get it :) Hopefully my last post may not be ?

Currently top balancing my battery pack before discharge. The one thing I am unsure of is that the total current is still @ a minus figure. Do I need to keep feeding the pack to get that to zero? The cell deviation has gone from 274mV to what is above now at 4mV within 8 hours. Currently...
