Solar PV -> Home Load -> Battery -> Grid as a general rule, overridden only when force charging on cheap rates; we are on Octopus Agile. A couple of days ago I noticed the app showing a home load being filled by the grid when our battery had 90% charge. Played around with some settings: By inserting 2014 as a password in settings, got to the ...
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.
Whenever a load is connected to the battery, it draws current from the battery, resulting in battery discharge. Battery discharge could be understood to be a phenomenon in which the battery gets depleted of its charge. Greater the current drawn by the load, faster the battery discharges. Battery discharge during idle status?
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.
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.
However, electricity demand peaks later on in the evening after the sun has gone down. Fortunately, nearby grid scale batteries can store the energy generated and discharge during peak hours. In short, grid scale batteries help shift electricity from times of low demand to times of high demand.
By the end of the Charge Period, the % Battery Charge will either be Charge Up To or the system will have managed to escape into Eco Mode and surplus PV will have raised % Battery Charge above Charge Up To. Further testing has led me to revise my views on this: When a Charge Period is in force, the battery is prevented from discharging.

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 solar to home/battery. Pulling 10kW for a shower will always use a good load of grid, the AIO is limited to 6kW max inverter, Hybrids 5kW or 3.68kW

Discover five reasons why Battery Discharge occurs and learn to understand the Battery Discharge Curve and the different charge stages of a solar battery.
Self-discharge occurs when the stored charge (or energy) of the battery is reduced through internal chemical reactions, or without being discharged to perform work for the grid or a customer.
Why is my PV system discharging to the grid when my battery is not fully charged? With your battery set to charge first, there may still be times it will discharge a small amount of AC power back into the grid. This is due to the battery management system which is there to protect the battery from being damaged.
It is an important factor for DC-DC connection. If you use DC power to charge the battery and discharge the energy for DC devices, you will need a battery with good round-trip efficiency. Battery Lifespan & Warranty. Battery lifespan is a significant matter for high-voltage batteries. In off-grid living, you need powerful batteries to power ...
Obviously I dont want it going to the grid so I''m wondering what setting I need to use to only feed the load? I previously had the inverter set to Load priority but nothing came from the battery. Any help would be hugely appreciated as to what the advanced settings need to look like to enable the battery to discharge when needed. Thanks

Battery discharge rates: Batteries have limitations on how quickly they can discharge power. If a household experiences a sudden surge in demand, like turning on multiple appliances simultaneously, the batteries might not be able to supply the required power fast enough. To prevent a blackout, the system may automatically switch to the grid to meet the immediate …

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 …
When the energy meter detects energy flowing from the grid to the house, it switches on the battery discharge circuits. There is a protocol that the BMS (Battery management system) follows to ensure the optimisation of surplus solar energy. The battery will only* charge when the solar is producing more energy than the loads are consuming.

My system is set so I can charge my batteries from the grid during an overnight low unit price period. I want to release unused power to the grid during high unit price periods i.e. at peak times, say, 4.00 to 7.00p.m. in the UK. Can anyone suggest how I might do this please?
Have just seen a video from a SOlarEdge battery owner who force discharges to the Grid at the rate of 2.5kWh during the Octopus peak rate time (4-7pm) to maximise his returns. Can we do that with our FoxEss batteries?

The description of "timed discharge" is "This mode will discharge your batteries to your home during a period you define". "to your home" suggests it should meet home …
Your battery will discharge energy to cover your household electricity needs. GivEnergy ECO mode is good for: Pretty much any user (hence why it''s the default mode) Users with a battery plus solar PV array ; 2. Timed charge . As the name suggests, you can set a timer for when your battery charges from the grid. Let''s say you can get cheaper electricity between …
Discharging Power: this is the discharge rate of your battery. A value between 1 and 100% which determines the amount of flow. Think of this as a tap, 100% is fully open, 1% would be droplets trickling through. Stop Discharging SOC: The battery level percentage at which you would like to stop your battery force discharging to the grid.
The description of "timed discharge" is "This mode will discharge your batteries to your home during a period you define". "to your home" suggests it should meet home demand, like eco mode, and not discharge to the grid. However, that is what it does – discharges at full power to the home and grid.
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. Here''s what I''ve done so far:

Have battery set to supply power when solar not available, but it''s also showing it''s feeding back to grid. Why?
Data from April 30th when battery discharge hit an all-time record in CAISO. Interestingly, it appears that batteries charged on that same cheap solar during the day have been able to take control of the peak management …
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. …
You can see the initial draw from the grid to charge the battery for a few hours overnight. [The early morning draw from the grid that morning was because we didn''t have the battery set to force charge until the end of the …
