Sustain current too high?

Sustain current too high? Hello Victron fellows, I have set some Li ion with Victron inverters, always for self consumption with PV inverters, but this one is cracking me up. This system consists in three 48V Multiplus II 3000/35 as a three phasic system, and an ESS assistant is set. The sustain voltage is 43V and cuttoff around 42V.

NEW Sustain Mode shifted to storage mode

1. The system when from Sustain mode over to storage mode. Everything was working great. SOC was being maintained at about 30% (13volts). What triggers that. I understand there is a 7 day timer but I thought that was only if it couldn''t keep up. 2. How do we switch modes using the CERBO GX. I''d had to have to open veconfig …

10. FAQ

10.3. Q3: Even when the battery is full, the system is still connected to AC-in. This question is typically asked by users or installers that are familiar with our previous configurations, for example Hub-1 or Hub-2, in a series installation rather than a grid-parallel installation. In that configuration the system used to switch to inverter ...

Feature request

Is it possible to change solar/wind priority so that after 7 days (or reaching the minimum voltage/SoC threshold) when it switches out of sustain mode and charges to 100%; That it doesn''t then stay in this mode forever but then reverts back to sustain mode after a programmable time, enough to allow cell balancing for LFP banks?

NEW Sustain mode and CHARGE TO 100%

Recently victron released solar and wind priority with sustain mode, and then a charge to 100% button when on. My question is. Can anyone tell me the mqtt topic that changes when CHARGE TO 100% is started? I have an external integration all using mqtt, and could really use this so I can publish this from Home Assistant. solar wind …

Min SOC is not reached

Min SOC is not reached - Pylontech US2000C - sustain. Some of our installations are going to sustain mode before they are reaching the min SoC set to 10%. The installation: Pylontech US2000C battery modules, MultiPlus II 48V Inverter, ESS assistant is loaded. I know I should change the dynamic cut off voltage and the sustain …

Sustain will always remain in operation. Disabling charge will not disable sustain. See ModbusTCP excel sheet for scaling and data types, available here. 3. Mode 3 in detail 3.1 Operation Mode 3 means you take direct control of the Multi itself by setting the

Verhalten Victron ESS bei SOCmin Limit (Sustain Ladung)

Problem 2: Ich habe 51,2V Sustain-Spannung eingestellt (16s System). Ich sehe häufig in Foren, dass die Akkus bis 47 oder 48V entladen werden. Gleichzeitig erscheint mir der Wert von 51,2V für die Sustain-Spannung aber realistisch, weil das der "Wohlfühl"-Spannung von 3,2V der Zellen entspricht.

Multiplus Low Batterie mit ESS

Hallo Forum, seid ein paar Tagen habe ich ein ESS mit drei Multiplus laufen. Lifepo4 Batteriebank 200Ah ist ein eigenes System mit einem BMS. Ein Wechselrichter blinkt laufend mit low Batterie. Welche Einstellungen wären korrekt. Batteriespannung ist 51,2V. Bitte euch um Unterstützung.

Sustain Mode (Prefer Renewable)

I also couldn''t tell it to Go to Sustain mode manually. However in order to trigger it, I have to go into the Advanced Settings of the Remote Console and choose to "Restart the VE.Bus system". Once that is done - it instantly Ignores AC (as Battery is definitely at 100%) - and continues to discharge as normal to the value I set in the …

New Sustain mode picking up shore power

On a boat with a Quattro running firmware 506 and a CerboGX running 3.10 and the new sustain mode enabled. When I plug into shore power when SOC voltage is above the sustain level set in the quattro, it seems the quattro does not immediately pick up shore power on AC IN2. I''ve verified that shore power is coming into the boat.

Charging LiFePo4

The charging current during the last screenshot is around 30-40A. I was on vacation for 2 weeks were i left the system run with these settings and no change e.g BMS is aggressive and turn off charge extremely many times during a cycle. I use 10% SOC. I believe the iCharger uses 3.65V in it''s LiFePo4 charge profile.

Solar and wind priority

It stays in this mode, called Sustain, for seven days; and if by that time there has not been enough solar or wind, it will run a full charge cycle, charging the …

Victron ESS dynamic cut-off config

(Sustain mode is when the inverter charges the battery at a low charge current to protect it from damage. Again, more important for lead acid batteries). So given that you already have DCL control and a …

Turn off Sustain mode when leaving dock?

aquabelle answered · Oct 13 2023 at 6:38 PM. Yes, i sometimes do start the genset when leaving the dock. For example, i have a gyro stabilizer which requires genset power, so if I''m going to sea i start the genset at the dock and switch from ShorePower to Ship''s Power (genset) via an external transfer switch. This tfr switch isn''t …

Sustain Mode EasySolar

Sustain, which Victron call absorption, is the fixed voltage part of a three or four phase charge cycle. Once voltage hits 14.4, AGM batteries are about 80% charged. …

Observing Varied Behavior in Multiplus: "Limit Internal Charge to Prioritize Other Energy Sources"

The initial incident occurred on 2023-11-11, during which the Multiplus maintained sustain mode as the system voltage was 13.26V, slightly above the configured sustain voltage of 13.2V. This allowed MPPTs to engage and raise voltages to 13.3V (as set by BMS: CVL=13.3V).

ESS mode 2 and 3

In Mode 1, standalone operation, the ESS control system tries to keep the power flowing through the grid meter at 0 Watt (so no power is taken in from the grid, nor …

Solar and Wind Priority configuration question and issue

Yesterday (2/16/24), I enabled the solar and wind priority feature on both Quattros. I set the sustain voltage to 13 volts on both units as the Victron documentation recommends for Lithium batteries. I enabled the feature through VE Bus System Configurator and uploaded the configuration file to the Quattros through the VRM remote configure feature.

It stays in this mode, called Sustain, for seven days; and if by that time there has not been enough solar or wind, it will run a full charge cycle, charging the batteries to 100%. This will make sure they stay in an optimal condition as well as be ready for a next use. Much more info in the link which will explain how it works. If solar panels ...

Multiplus goes into Sustain mode when disabled

Multiplus goes into Sustain mode when disabled. I have a Multiplus 12 1200 50 which was previously configured using Sustain mode. Sustain mode is disabled on the inverter as I am using an AC Ignore VS during the nice sunny weather. This morning the inverter switched Sustain mode on - briefly - until the MTTP kicked in as the sun …

The inverter in my ESS system is stuck in Pass-Thru mode?

As the system is set to work with a grid meter. If the setting in VENUS is set to enable grid meter, and no meter is available, or it is not functioning correctly, this can lead to a pass-through state. Disabling the grid meter setting immediately re-activated the inverter function for the critical loads. Though now the additional AC solar and ...

Pass Through mode on Multiplus

However, I did run across the "Passthrough" mode today. If you change your charger settings to disable (ie: not charging your battery) within the VE Bus System Configurator program you will enter passthrough mode. This will allow AC to passthrough without charging your battery. If you have a CCGX you will see it say Passthrough on the Victron ...

In an ESS system, what is the difference between Sustain …

The sustain voltage is a floor voltage, so regardless of either of those settings, the battery will not discharge below that sustain voltage point. In both those …

Multiplus II Stuck In Sustain Mode

The batteries charged and ESS assistant was set up using VE Configure 3. I set the charger absorption and float voltages to 51.7v & 51.0v respectively. My VRM portal is showing batteries at 100%, 52.3v and inverter''s in Sustain, even though I''m drawing a few kW from the grid. The Pylontech''s BMS is on CAN-Bus as recommended.

ESS mode 2 and 3

It allows for full control of the inverter/charger and the power from- and to the battery. The power flowing to the batter (or more precise: to DC system attached to the Multi) is equal to the AC-In power minus the AC-Out power. In Mode 3 you have to create your own control loop, and update the set-point frequently.
