Ever since Nov 12-13 there’s been no battery discharge. The battery seems self-discharge to 97-98% by the time the sun comes up, then the solar charges it back to 100%. But evening demand that used to be satisfied by battery discharge is now coming from the grid.
Solis Cloud- The battery does not charge or discharge. Solis Cloud- The battery does not charge or discharge. hi, we had solar panels, an inverter and pure drive battery fitted. So far we have used a fraction of electricity produced. The battery does not charge or discharge.
If it has communication but wont discharge, it's probably just configured in a such a way that never allows discharge. Ideally, your battery installer would help you reconfigure that through the SolarEdge website. How Much Do Solar Panels Cost?
When a solar system undercharges, the batteries may not receive sufficient energy to reach their best charge levels, resulting in reduced capacity over time. This can be caused by factors such as inadequate sunlight exposure, shading from nearby objects, or incorrect settings on the charge controller.
Overcharging problems in solar charge controllers can substantially impact battery life and pose potential safety hazards. When a controller fails to regulate the charging current properly, it can lead to excessive voltage being delivered to the battery, causing overcharging.
When the solar panels generate high voltage, it can lead to overcharging, which is detrimental to the battery lifespan. This issue may stem from a malfunction in the MPPT solar charge controller or the solar panels themselves.

When we say that we are discharging the power supply unit, we are actually discharging the residual charges from the capacitors. Generally, Switched Mode Power Supply Unit (SMPS) is widely used in the PC. There are three methods to safely discharge the capacitors of the PSU. Power Button Discharge. Turn off all the power supply to the PC from ...
I bought some EVE MB31 314 Ah (tested at 330 Ah actually) cells to make a 48V LiFePO4 battery. I''m in the middle of top balancing them with a 2800W, 80A max output hobby charger (iCharger 4512DUO), but quickly realized I didn''t have a power supply that could supply more than ~150W to the charger (got about 30A from the charger) .
I tend to set mine to 50 or 60% reserve though so overnight I easily deplete it down to that level. During the day if reserve is set to 60% and battery has been charged above that. I do see that it will discharge battery first if energy …
That screen will tell you how much power your system is capable of providing continuously. The 5 in the 5P name reflects approximate storage capacity, not power output. And yes, there''s something amiss with your CT connections. You shouldn''t be drawing any power from the grid to charge batteries after solar stops for the day.
Discharge rates depend on the charge controller, even for an LG Chem RESU10 which can store 8.8kWh of energy, the charge controller installed may only be able to charge/discharge 2kW at a time. So, if the battery can only deliver 2kW of power to the house, this is just enough for a kettle with a little spare for other requirements.
(BMS is a common port for charge and discharge) The issue I''m running into is that the inverter/charger will not turn on at all unless it sees battery voltage on the 12v terminals. So, it will not turn on and charge the batteries because the BMS isn''t letting it see 12v and it won''t turn on even with shore power.
I''ve got Solaredge electronics, an LG Chem battery, and Mission Solar panels which were installed in the summer of 2018. All was good since I purchased the house in the summer of 2019 - battery discharged to 20% every night. Ever since Nov 12-13 there''s been no battery discharge. The battery seems self-discharge to 97-98%
The battery does not charge or discharge. Installer says it''s a fault and are waiting for pure drive- I think it''s set up as it charged from the grid at one point and discharged to the house, but they …

Here''s my setup: Sol-Ark 15k Inverter 2x16s1 LifePO4 battery banks (EVE LF304), Overkill Solar 48v 100A BMS Since there''s no way to get the BMS to communicate with the inverter - or each other - this is an...
Meanwhile the Power Supply holds at 13.6 volts. Any loads turned on, the power comes from the Power Supply (charger) while the battery sits there and FLOATs. If the current demand exceeds what the Power Supply (charger) can supply, or if the charger is turned off, the batteries are already on-line, take over and supply power.
So, you won''t need float charging for the LiFePO4 battery pack. So, ensure you do not have a float charging option in your power supply. But even if it does, do not forget to switch it off. If you can''t do that, at least …
Everything depends on how much solar power is available for the system. In a typical solar power setup, the inverter does not actually charge the battery. It is the solar panel that powers the battery bank and the inverter …
Hi, recently installed the Solax X1-AC 3.6 and Triple 5.8 battery. Works, shows no fault. Charges from grid to 100% and discharge 10%. Problem is that the house loads are not using battery. Just racking up the house meter power. On Self Use so battery should give priority to house loads.. Chint...
A C rate is a fixed charge or discharge current that is equal to the charge or discharge current divided by the amp hour rating of the cell. A rate of 1C is a rate equal to the amp hour rating of the cell. 2C is likewise a rate that is double the amp hour rating of the cell. 0.5C is a rate equal to half of the cells rated amp hours
discharge to supply house loads while there is still energy in battery; emergency charge from grid if battery gets really low). Over here in England, I''m charging from grid 2-5 AM and doing a trickle (just enough to be more than typical house loads) discharge 4-7 PM (which is a higher-rate than normal, on my tariff).
Re: Solar Power - Charge and Use at the same time? many other batteries are not getting a proper recharge while they allow you to use them while charging. car batteries are always running a deficit and would benefit from a small regulated solar panel to finish off the charging process. car battery charging is a compromise that the auto industry uses and is a cheap way out of …

Another way to look at it, for every 2 hours of solar irradiance you get, you can charge 1 e-bike battery/day, with enough reserve battery capacity to charge 3 with no solar charging. This does not take into consideration inefficiencies. DC to AC to DC conversion may be only 75% efficient.
The blue-tooth battery app shows full charge, the battery charger is showing full charge. But, nothing coming into the inverter, and the LCD battery display scrolls down to zero and goes off as soon as the battery …
