Battery discharge and feedback to the grid principle
The proposed converter enables Electric Vehicles (EVs) not only to charge their batteries from the grid but also to discharge excess energy back into the grid through the Vehicle-to-Grid (V2G
Solis inverter program battery charging from the grid
With regard to preventing the Solis from using the battery at certain times, one way you can do that is to set a TOU slot to "discharge" but set the "discharge current" to zero amps. On a related note, it sounds like you''d benefit from purchasing a 3rd Pylontech so you can continue using the cheap electricity until the next night rate kicks in.
How to Trigger Force Discharge to Grid from Battery
I have managed to discharge my solax battery to grid. I programmed an Arduino Nano to reply to the inverter claiming incoming power of 5kw expecting the inverter to go to maximum output. I have this set to address
how do I stop grid export?
To prevent a race situation between the battery storage and this device you set a threshold e.g.200w and a delay say 5 secs to allow the battery a chance to react first.

Depending on the battery you have installed (hybrid, or AIO), you could be limited to a battery discharge of 2.6Kw, 3.6kW. ECO will balance charge and discharge from
How to Limit Battery Discharge and Use Grid Power with Victron
How can I configure the system to limit the battery discharge to 60A and draw the additional power needed from the grid? Any detailed steps or settings adjustments would be
SolaX X1 Hybrid discharge battery to grid #417
Hi. Looking to discharge my battery to grid due to arbitrage available with, and encouraged by, my supplier. If I set export limit to say 3000W, change to Manual Mode, change Manual Mode to Force Discharge, I only get a small amount of export to grid- I assume solar input minus current house load.
Grid pull when discharging from battery
If batteries are being used (i.e peak hours) then stop all possible grid importing of power (at the moment I''m getting between -100 watts and +100 watts in short bursts).
Electric vehicles as distribution grid batteries: a reality check
The current transition towards electric mobility implies that a significant portion of electricity is drawn by and stored in the electric vehicle''s (EV) batteries. Vehicle-to-grid (V2G) technologies can potentially give distribution system operators access to such energy to provide ancillary services, while remunerating the vehicle owners for their availability to participate.
Discharging to grid when set to Consumption Type Home Demand
Thanks, but hold your horses. The system is even more complicated than I had thought. There are some real surprises, e.g. when you''ve been charging in a Charge Period and the Battery Charge reaches Charge Up To, then provided Battery Charge < AC Charge Upper SOC % Limit, the system stops charging the battery from the grid and switches into an
Discharging to grid when set to Consumption Type Home Demand
I''m a new user and have tried to setup so battery charges up between 2am & 4pm and then discharges between 4pm and 2am. Discharge mode is Scheduled and
How to Limit Battery Discharge and Use Grid Power with Victron
My issue is that when solar energy is low but the grid is available, the Quattros draw more than 60A from the batteries, which is bad for the battery health. I want to ensure that when there isn''t enough solar power from the Fronius inverter, the Quattros only take a maximum of 60A from the battery, and the rest should come from the grid.
GivEnergy ECO mode & other battery
As the name suggests, this mode allows you to set a timer for when your battery exports energy to the grid. Under timed export, your battery will discharge at full power.
Export to grid battery settings
I''ve now reduced them to 12A. My hope is that with this adjustment, during periods of high load, the battery will discharge at a lower rate and rely more on the grid. This way, when a large load like the oven is turned off, there won''t be excess power feeding back into
Why does my battery discharge to the grid, or charge from the grid?
Discharging: The battery will only normally discharge when the energy meter senses power coming from the grid (and there is charge available in the battery).
Ess drains batteries into grid

Discharge battery to the grid
<p>From 4pm to 9pm I have excess energy in my battery that I want to discharge to the grid to be able to run a negative consumption on my net metering. Especially during a heat wave, I can make quite a bit of money if my net metering is negative during peak hours. </p><p> </p><p>Is there a setting to discharge battery to the grid during peak hours? </p>
Forcing a battery charge from the grid? : r/enphase
Menu > Settings > Battery > Advanced Settings (the slider menu in the top right) > toggle charge battery from the grid In my experience, there already seems to be a "smart" feature built into the software whereby my battery will charge from the grid if there isn''t enough solar to charge it in time for peak hours (my system is set to savings mode with optimization based on the utility
Control of Victron Battery Discharge and Grid Power
I want to control Victron so that I can decide when Victron is allowed to discharge the batteries at night or instead draw energy from the grid. As I found out, I can achieve this via MODBUS registers 2704 and 2705. As soon as I set register 2704 to 0, the system starts drawing from the grid. Additionally, I need to set register 2705 to 0 so that the battery is not

Grid-Scale Battery Storage
The current market for grid-scale battery storage in the United States and globally is dominated by lithium-ion chemistries (Figure 1). Due to tech- being discharged to perform work for the grid or a customer. Self-discharge, expressed as a percentage of charge lost over a certain period, reduces the amount of energy available for discharge
Issue with ESS taking power from Grid
Feedback from Victron was ''fluctuating grid frequency''. The grid frequency varied with something like 0.25Hz, and this caused the system to behave irregular. This was due to industries close by. The system works 100% on weekends. Keep batteries charged, prohibits any battery discharge unless grid fails.
Why is my battery power getting sent back to the grid (as well as
It''s the sum of the grid export and house load. One or both of those is probably inaccurate at such low loads - the grid export number especially, even more so if it''s three phase. This is very much in the realm of fiddling at the margins - if my battery was showing only 85W discharge overnight I''d be cheering and moving onto other problems.

6 FAQs about [Battery discharge feedback to the grid]
When does a battery discharge?
The battery will only normally discharge when the energy meter senses power coming from the grid (and there is charge available in the battery). In the normal operation of electrical appliances, they will be switched on and off by the end user, or in the case of heating and cooling, a thermostat will control loads on and off.
When does a solar battery charge & discharge?
The battery will only* charge when the solar is producing more energy than the loads are consuming. The battery will only* discharge when the loads are consuming from the grid. When the battery charge falls below the minimum allowable SOC set by the BMS, the battery will be force charged from the grid until the SOC reaches the minimum.
When does a battery stop charging from the grid?
This has the effect of charging the battery up to 100% from the grid starting at 01:00 and ending whenever it gets to 100%. This may well be after 04:00, so some of the charging uses standard-price electricity. My scheme stops charging from the grid when off-peak pricing ends. Between then and 4 pm, the battery would not discharge.
What is battery charge settings / Dynamic / scheduled / dynamic?
Battery Charge Settings Battery Discharge Settings Discharge Mode = Scheduled / Dynamic corresponds to Enable DC Discharge = On / Off. Setting Discharge Mode = Dynamic also changes Enable Eco Mode from Off to On but otherwise leaves it unchanged
What happens if battery charge rises or falls in Eco mode?
As Battery Charge can either rise or fall in Eco Mode (depending on whether PV > Load or PV < Load) this can either lead to a sustained rise in Battery Charge for the rest of the Charge Period or to Battery Charge dropping back to equal Charge Up To, when it reverts to Load from the grid; PV to the battery.
How does battery charge work?
Battery Charge = Charge Up To. When Battery Charge reaches Charge Up To, the system switches to Grid = Load mode: Note that: Battery Charge cannot fall in this mode (unlike in Eco Mode) and will rise if PV is being generated.
