A Split Phase system with two Quattros 48/10000/140-2x100 120v with Product ID 2754 was working with Venus v2.42 and we performed an upgrade of firmware on the Quattros to version 469.
After the upgrade of both Quattros we reconfigured via VE Config all the setting by uploading a saved version of the configuration. The setting where saved with no issues.
Once we brought the System online the Venus shows "No ESS Assistant found". We proceeded to go back and remove the assistant using VE config and adding it again, but the Venus still does not see the ESS Assistant.
Is Quattros firmware 469 for Product 2754 compatible with Venus OS 2.42? If not what would be the recommended software versions? If they are compatible what can I do to get the Venus to recognize the ESS Assistant from the Quattros?
Would I be able to adjust settings (like I can do on my Android cellphone for connected Bluetooth devices) by connecting my Cerbo-gx to Windows PC (running Victron Connect software) using mk3-usb dongle adapter? Thanks
I have 5 Victron Energy SmartSolar Charger MPPT 100/20. They are charging the same LifePO4 battery. The battery preset is set to Smart Litium preset. They work together in VE Smart networking.
Two of these chargers are not charging now for a couple of days. By checking one of the charge controllers it seems to be a software issue (regarding that two different voltage should not appear in the same moment).
Disconnecting PVs and the battery didn't help. Reset to default didn't help. Leaving the network also wasn't the solution.
The PV voltage is always just under the battery voltage, but if I use a multimeter the voltage should be fine (e.g. 25V in the software instead of 30V measured).
Does anyone has any idea?
Thanks in advance!
I have a "pylontech" (reality unbranded but shows up correctly in cerbogx CANBUS). connected to cerbogx
also multi RS connected to the VE.CAN on cerbo gx.
Cerbo GX shows correct battery state of charge.
however, the Multi-RS still shows the incorrect "state of charge" for the pylontech battery in its own "victron connect connection".
how do I rectify?
why can’t Victron Connect maintain its connection to a device? e.g. a battery monitor.
I want ro keep an hours long record of the Trend view, to monitor Volts and Amps, while testing a new alternator regulator. As soon as I look at another app, or resize a window in iPadOS stage manager, Victron Connect loses its connection.
Anytime I switch Apps, it has to ‘reconnect’. This seems different to every other Bluetooth app. ‘Frustrating!!’.
Hi everyone. First post here. I searched for quite some time, but couldn't find an answer.
I have an Multiplus II 48/5000/70-50 working fine as an ongrid system. Just one small problem:
There is no power on the "Auxiliary power supply 12 V 100 mA" (Terminal J). Is there a fuse (wich could have blown, though there was never any load connected) or any action nedded to activate the power?
I appriciate any help!
I have a cliente looking at 2 EVCS on one system connected to AC2 out of the MPII's but the following questions come to mind;
1) When both are configured to Auto to use excess solar, how will it handle this? Will it share the available excess power, prioritise one,...?
2) Will both chargers show up seperately in VRM?
3) Can I have one on auto to use surplus and the other programmed?
The setup will be ESS with the following as the main components;
3 x Multiplus II 48/5000 in parallel (15KVA 1 x 230V)
1 x RS MPPT 450/200
1 x MPPT 150/85
12 x Pylontech US3000C
1 x Cerbo GX
37 x Hyundai HiE-S440HG
Thanks in advacne
I'm planning to install a new system with a multiplus-II 5000 but I think that power will be not enough within some time (in a 2 years time frame). I'm planning to pass to a parallel configuration in two years. I will be able to add additional PV modules and batteries (Pylontech) and use more power and also to have a level of redundancy
Considering that is possible to have only a GX device what do you think is the better option:
1. Install now a multiplus-II GX now and then install a second multiplus-II GX, disabling the GX part
2. Install now a Multiplus-II and a Cerbu GX and the install another Multiplus-II
3. Install now a Multiplus-II GX and then, in parallel a Multiplus-II NO-GX
4. Redundancy is not required, use a Multiplus 8k or 10k now and a Cerbu GX and upgrade only batteries and PV modules
I replaced my CerboGX and I would like to transfer the old data to the new installation.
I followed the procedure, but I still have 2 installations in the VRM
- the old: ID c0619ab38582 - USEDASREPLACEMENT
- the new : ID c0619ab38582
I have this message if I renew the replacement.
Failed swapping Color Control GX. Is it already transferred?
Someone can help me?
im struggling with system design and what I need. ideally I would like everything to run off of backup batteries as well But my system is split already.
So I have a Henley block from the main income splits the garage consumer unit and the Houses consumer unit. I have a 3.3kW array, solis ac coupled inverter to the houses consumer unit. The Batteries and Victron Inverter would be installed in the Garage.
ideally I would like the solar, loft kitchen and the garage sockets to operate in a grid down manner still ie so I would have to split out the house consumer unit or run the mains to the garage and take it back to the house from the inverter but also have provisions to switch back to grid in the event of inverter replacement.
I looked at the 48/8000 Multiplus which is capable of 100Amp switch so would run the house without overloading, the 48/5000 is another option but would see me having another consumer unit in the garage and another in the house inorder to split the garage sockets , and in the house the loft, kitchen and solar.
I am aware I’ll need to run SWA cable depending on the options of inverter. I’m capable of running two 25mm SWA cables to satisfy 100Amp draw. I could run Cat5e Cable to the garage for the ESS but I have no idea how many pairs I would need to run to the cerbo GX so that I could monitor the solar as well as the incoming from the grid. Also how many Pylontec batteries would I need for each Multiplus 2?
Any help with design would be appreciated and PS is there Victon installers in Buckinghamshire?
Looking at upgrading my RV solar to a 3 panel system on a new MPPT 100/20. Existing is 2*100W on an older controller. The older panels are discontinued so I am purchasing a 3rd panel that is not identical. Battery bank is dual 225Ah golf cart (in series = 12V)
New system would be:
2x Renogy 100W Panel modules
1x Renogy 175W Panel module
I've calculated these 3 panels can be run in parallel with only a 2.68% loss due to the difference in panel specifications. Panels will need to be individually fused due to the max fuse rating in the event of a short.
The updated array will output 365W at 17.95V @ 20.33A.
The Renogy calculator shows it's 129% oversized. Should be a good amount due to primary usage in the northern hemisphere, and they will be flat mounted.
My primary concern is: I've calculated the array short circuit (5.75A + 5.75A + 10.31A) = 21.81A. This number is tripping me up with regards to the 100/20 recommended max short circuit.
Does this prevent me from using the MPPT 100/20? Do I need to be looking at the MPPT 100/30?
Does anyone have experience with installing a soft starter between a Quattro / Multiplus and a 1-2 kW pump? I tried 2 solutions but both systems destroyed my 230V network.
Does anyone have a suggestion for a good working soft start solution?
In the Firmware Changelog for v3.11 under "Improvements" there's a line that says "Add support to relay remote control mode, which allows the user to manually select the relay state."
How does one use this relay remote control mode? Is it accessible via NodeRed?
Hoping someone can help with an EasySolar 48/5000 issue when charging Pylontech (us3000 x4) batteries with a Yamaha EF7200 generator. For some reason the Easysolar will only pull 2800 watts from the geni even though the Input current limit is set at 20A. Furthermore, if I draw load in the house the generator will ramp up to service it. This leads me to believe that the problem lies in the easysolar to battery charging settings. Charge Current Limit (CCL) in Battery Parameters setting is at 148A. This has got me completely stumped…. Any ideas/help would be much appreciated.
