I have a 3 year old Easysolar 48v 5000/ 70a system with 3 Pylontech US2000C batteries and a backup generator as a full off grid system.
i have a fault where the batteries would get stuck charging at 88% and then clear after a few hours and charge fully, this problem has now got worse and they get stuck in the 60s and and around 73%, if they clear that they get stuck a 88%and will not pass this level
i know there is more solar available as when i put load on the system the pv charger increases dramatically .
the system also shows a constant charging of 439w regardless and this does not change.
i have added 2 photos one with load and no load to show the differences.
i would be very greatful for and help or ideas
I just had an alarm via VRM that the newly installed MPPT RS450/100 which has been operating perfectly for a few days is now not charging the battery and is showing the following error:
|Solar Charger - MPPT 450/100 HQ2142HTVCQ ||Automatic monitoring||Error code: #200 - Internal error|
The rest of the system is working fine although my customer has persistent bleeping from the unit.
Brief overview of system:
Pylontech US3000C x 7 modules
MPPT RS 450/100
3.4kw of PV in two strings
Can the fault be addressed remotely, will it need a visit or is it a warranty claim?
Any advice gratefully received as I cannot find this error code listed elsewhere
When we have load shedding the inverter kicks in automatically. When the power comes on again the inverter gives a fault and says AC Disconnected. if you switch the inverter off and back on the inverter works again.
Hi, Has Victron sorted an option for the earth fault monitoring of a mppt 250/100 ?
Assuming it would send a signal to a GX device for an email/alarm alert, or close the relay on smart versions, to be able to trigger an audible alarm?
Any options appreciated.
Faulty Cerbo GX devices
Is anyone aware of a manufacturing defect affecting a recent batch of Cerbo GX devices, especially when used on 48V systems?
We have 2 separate customers, who have both reported 2 failures each, of Cerbo GX units when attempting to power them up from the 48V DC bus. The inline fuses remain intact, and the polarity is correct. One user reported hearing a 'pop' from the upper right corner of the unit, when they connected the power lead.
Not flashing simultaneously, but alternating. No explanation in manual. Two questions that I could find on here with no real answer posted.
Setting up trailer with full Victron system. Have been running MultiPlus for a month or so with no problems, running Venus on raspberry Pi. Just today got first solar panels installed on roof and wired in to 150/70 Smart Solar. Worked great for half the day, until I connected with Bluetooth through my phone on the connect app. Connected fine, then prompted to do firmware update, so proceeded. It updated fine, then seconds later prompted for another firmware update. This one will last a range of 2% completion to as high as 86%. Eventually I give up and go look at the MPPT and find the lights flashing alternately. I look in the manual, no explanation. I measure the voltage with multimeter, 56 volts coming from the panels (sun was going down by this point), 12.3v on output. Not charging, obviously.
I did updates on the 5 other 100/30 Smart Solar in the install, and they go just fine.
Anyone able to help?
I have an Orion TR Smart 12/12 18a (Isolated) which I believe may be faulty.
Actions I've taken to remedy it
I believe I have exhausted all options however I thought I would put it out here to the brain's trust. The device is new to me so it's not a case of it was working for me before.
Here is the screen of the charger in Bulk Mode, reading the voltages correctly
This screen shows that the BMV smart shunt is showing no amps to the battery. Note the 0.00a under the SmartBMV line.,
My settings are below. I did try dropping the start voltage to 13.6 to see if it made a difference - no difference.
I'm assuming this unit is faulty ...
Victron Quattro 10 with 30kw Dyness and 16kw solar PV through 3 X 450/100 rs mppts. Setup as ESS. Picking up error #35 alerts followed by a high voltage alarm within notifications. System shuts down and restarts after device list - quattro - switch to on ! Advanced shows no over voltage in the mppts including no over current. Altered the DVCC to 51v maximum hoping this helps but unsure as voltage on battery side spikes upwards of 55v during #35. Faults are occurring in the evening and battery at 100%
[image]Running 24V system with 12x 2V 1500ah Mastervolt traction gel batteries, all on their side. Batteries are connected via connector plates Inherited this ESS, it's located under the house on clay soil and some structural plywood. 100kg each, not surprisingly the ground has settled a bit over the last two years and the top two middle batteries have slid back. The terminal connection held strong and the plate/terminals have been pulled out a couple of centimeters.
Just doing some work on a customer vehicle and updated Buck-Boost DC-DC Converter 50A and TSC Config to latest as customer was having flat starter battery issues. Now cant get it to charge second battery. Tried downgrading to TS Confid 188.8.131.52 but no different
and help would be appreciated
Output voltage is measuring correctly (with a multimeter) and charges with appropriate current, however the app indicates it's charging at around 18V and 16A (which I know to be false). Latest firmware and app. I've tried cycling power, reinstalling app, reducing output current to 8A, Power supply mode at both amp settings, all of the modes - nothing changes the displayed output voltage from around 18V. Any solutions?
Does anyone have a link to where I can find guidance on testing the Aux contacts on a Multiplus II GX unit? I have 2 non-operating Aux contacts. The only thing that has been connected is 2 Victron 40A CT sensors and after a firmware update the unit appeared not to be working to its full capability. No VRM graphic any longer for the PV and no working CT sensors.
I connected two small 300W inverters to the load output of my SmartSolar 100/20. These draw about 16A (8A each), and are working ok.
What is not working at all is the load output control. It is stuck on. I can’t turn it off by any means.
I unplugged the jumper - this allowed the state on the app to toggle between on/off, but the whole time there was output on the load terminals.
I tried setting Rx pin to remote on/off - no difference
Streetlights are turned off.
I’ve tried toggling between the other load output schemes, various restarts, etc.
The current/power measurement is also wrong - flickers between 0 and a small value like 4W, when in fact 600W are being drawn.
This post is remarkably similar: https://community.victronenergy.com/questions/78878/victron-bluesolar-mppt-10020-load-output-is-always.html
So I’m wondering if these inverters could have fried the MOSFET that switches the load?
Quite disappointing if so - brand new charger fried. Seems like a protection diode would have kept the circuitry safe.
Is there anything else I could try before I return it to Amazon?
I have an Orion tr smart.
It's wired via dual 6mm cable to an Anderson plug on my Isuzu. Then is connected along with an MPPT to a lithium battery bank.
When I connect the DCDC tr smart, it turns on, the Bluetooth light starts flashing and I can connect to the unit.
It will come on to charge for a few seconds and then drop out, the input voltage drops to around 6 volts.
it will then go back up to 13.8v at input input and charges the bank.. then after a few seconds will drop down to 6 volts again... the cycle repeats.
Any help would be appreciated
I have run a separate twin core cable directly connected to the battery in the car and straight into the Orion smart, therefore eliminating cable issues run in the van and car.. and still same problems.
Have bench tested the unit and seems to work ok.
I am wondering Would I need to add another earth from the car chassis to the negative bussbar in the van ? or is the twin core ok?
