Ich hab den Grid Setpoint nun auf -50W gestellt. Im VRM wird mir nun fast immer ein negativer Wert zwischen 0 und -75W am Grid angezeigt. Hab aber gerade mal am Zweirichtungszähler im Keller nachgeschaut. Dort sprint der Bezugszähler immer noch zwischen 15 und +50W hin und her. Und der Einspeisezähler ebenfalls in diesem Bereich.

Wenn Dein Standard/Default Grid-Setpoint NULL ist und Du diesem immer um den EM24PV-Wert verringern willst (Nachts dann wieder NULL, weil PV = NULL), dann nimm den
Hi all, I have an ESS system (Quattro, 20kwh batteries, Solar PV) and am trying to understand Grid setpoint and the quite large instantaneous fluctuations around it. e.g when set to 20W, i''m seeing a range of 150W draw from grid to 100W feed in to grid (presumably driven by the variations in load and PV generation).
How can I limit the input power when: ESS setpoint is set to certain value (let''s say 2000W) Desired minimum SoC is raised big. It''s starts charging automaticly at full power, and not at the desired ESS setpoint. I don''t want to limit the current, because on a 3phase system the result is far from close to 2000W. The point would really be to charg at the desired Wattage.
I have a basic understanding that grid set point is used to target a constant draw/send rate from the grid. For example: 30w draw rate target. I understand that by setting this to a positive number people can use the feature to prevent the inverter from leaking power to the grid in the seconds after a dynamic load has shut off.
I''ve enabled the ESS Assistant in "Keep Battery Charged" mode. The grid metering is set to inverter/charger, and the grid setpoint is at 0 W. My goal is to use the battery like a UPS—only activating it when the grid is unavailable. According to the Victron manuals, my configuration should be correct.
The load is a fixed amount. You can vary the grid point which then lets the system work out what happens at the inverter. load - inverter= grid point. ie if load is 100 and inverter is putting out 100 then grid point = 0. However we vary grid point and the system uses this to calculate what the inverter is doing. so . load - grid point = inverter
Both have the same settings and ESS Assistant applied. The Probem. ESS is unable to reach the SetPoint (0 Watts). The CerboGX shows that when AC-OUT (The House) is consuming 500W, ESS seems to discharge too much from the battery and therefore exports 150W - to the grid. This figure drifts further when the load increases. Thoughts
This is a project to implement dynamic ESS -- the buying and selling of electricity when pricing is attractive -- in Venus itself. It was previously implemented as a proof of concept in Node Red. The proof of concept uses. the ESS grid setpoint (to force an export) Feed-in excess DC-coupled PV; Scheduled charging (to force charging, or "idle" mode.

Introduction Important: When installing a single-phase ESS in a system with a three-phase connection to the utility grid, make sure you install the ESS on phase one, L1. Temperature
Grid tab: configure the country code. A password is required: ask your supplier. More information in VEConfigure: grid codes & loss of mains detection. Note: If you leave this setting as ''None'', the system will not supply battery energy to support local AC loads when the grid is connected. You do need to change this setting even if it is your intention not to export DC energy to the grid.
Placing it under Settings -> ESS -> Debug causes some confusion for me. Has this been placed here for convenience while monitoring the values? 2) Does anybody have an example of how the "grid setpoint" should be calculated? i.e. Use System Overview - DC System - DC System (W) on VRM portal to determine the max value and set it to that.
I found a temporary solution with setpoint at 100w+. But I don''t want to take it 100w from grid when it''s sunny outside or when I''m using the batteries. My System: 2 x Multiplus II 5000/48 (paralell), 1 x Smartsolar Mppt 150/100, 1 x Smartsolar Mppt 150/70 Tr, Bmv-712, Venus Os 2.90, 3x battery balancer, battery bank 500Ah at 48v, 7.2kw solar
An Energy Storage System (ESS) is a specific type of power system that integrates a power grid connection with a Victron Inverter/Charger, GX device and battery system. It stores solar energy in your battery during the day for use later on when the
I have now tested changing the grid setpoint in VenusOS 3.42 to -1000W in the ESS settings: DESS deactivated: grid setpoint is maintained. DESS activated: grid setpoint is unfortunately still ignored. I would like to have it set to -10W to prevent buying from grid as far as possible, which also works with DESS activated.
This sets the point at which power is taken from the grid when the installation is in self-consumption mode. Setting this value slightly above 0W prevents the system from feeding back power to the grid when there is a bit of over-shoot in the regulation.
The European energy storage market is booming with Germany leading residential adoption (+58% YoY) thanks to €500/kWh subsidies. Italy's new tax credits drive 5.2GWh commercial deployments, while UK grid-scale projects exceed 8GWh with 2-hour duration systems. Key selection criteria: German-certified safety (VDE-AR-E 2510), 10+ year warranties, and VPP readiness. Top-performing products include Sonnen's hybrid inverters (98% efficiency) and BYD's Blade Battery (12,000 cycles @80% DoD). For snowy regions like Scandinavia, consider Huawei's -30°C compatible systems. France mandates carbon footprint declarations - Sungrow's ISO-14067 certified solutions gain preference.
For European homeowners, 5-10kWh systems with 3-phase compatibility are ideal. Top picks: 1) Tesla Powerwall 3 (13.5kWh, 97% round-trip efficiency) for smart home integration; 2) LG Chem RESU Prime for compact urban installations; 3) SMA Sunny Boy Storage for retrofit projects. Critical features: EU-made battery cells (exempt from CBAM tariffs), dynamic tariff optimization (like Octopus Energy integration), and fire-safe LiFePO4 chemistry. Southern Europe demands 85%+ depth of discharge capability, while Nordic markets require -25°C operation. Always verify CEI 0-21 compliance for Italian grid connection and EnWG certification for German feed-in.
