This wear problem is what causes older and worn computers or phones suddenly turn off when they "still have 20% left" Their BMS is not smart enough to know the battery health. This is unacceptable in a car so we get smarter BMS systems to keep track of how much energy there actually is for use. The Tesla example is real how ever.
Never allow the Battery to fully discharge. Even when Model 3 is not being driven, its Battery discharges very slowly to power the onboard electronics. The Battery can discharge at a rate of approximately 1% per day, though the discharge rate may vary depending on environmental factors (such as cold weather), vehicle configuration, and your selected settings on the
If the solar power is too low, the batteries will drain their charge and eventually your inverter will turn off and batteries could become damaged if the wrong settings are in place. Too high a voltage in a battery bank is either due to an improper setting in the charge controller or in the inverter''s charger. Depending on your battery type, it

When does
Some controllers with user-configurable LVCs will have overly cautious defaults, like 42v for a 48v battery. LVC doesn''t work based on resting voltage, so even if your battery was resting at 46-47v after it cut off, LVC might still be the culprit if it dipped down to, for example, 42v for a moment while under load.
Charge controlers have an adjustable high voltage set point, so the batteries are not over charged. If you place a relay circuit that disconnects the batteries from the inverter so the voltage does not fall below the 12.06 50% level it would reduce damage to the batteries. When the battery level reaches your desired turn off, you adjust the
From the manual for the Exceltech it looks like the remote switch is a toggle switch so that would allow for simple control of the inverter. From what I can tell the Kid has a controlled DC output so its low voltage configuration can be used to turn a relay on the load output on / off and in turn that relay connected across the Exceltech''s remote on/off terminals will turn
Turn Off All Lights When the Vehicle is Off: Turning off lights, including high beams, when the vehicle is not in use is essential to prevent battery drain. Leaving headlights on can significantly reduce battery charge over time, particularly in older vehicle models.
