Solar container battery continues to discharge

Can you store a fully discharged battery on a solar panel?

With lithium it is less likely, but storing a fully discharged battery should still be avoided. All batteries will discharge at some point, and if there is little to no power left, it will damage the internal circuitry. As many solar panel users will point out, using a charge controller is one of the best ways to prevent unexpected battery drain.

What happens if you put non-rechargeable batteries on solar lights?

When you put non-rechargeable batteries on your solar lights, the light will try to recharge the batteries. Although non-rechargeable batteries can handle a small degree of recharge, prolonged recharge will cause them to explode. The explosion of the battery may ruin your solar lights or leave you with a lot of mess to clean up.

What happens if a solar system doesn't have battery storage?

If you have a solar system without battery storage and you experience a power outage, the solar system will automatically shut off. Electrical code requires that solar systems shut down during power outages so they don’t accidentally backfeed live power to the grid if the utility company has repair workers trying to fix the lines.

Can a faulty charge controller affect a solar system?

A faulty charge controller could lead to sudden voltage spikes or drops, affecting the battery internal charging system. The inverter is probably the most sensitive part of a solar system and problems with it could disrupt the battery charging capacity. Regardless what battery type you use, proper maintenance and use are essential.
