The voltage of the solar battery cabinet lithium battery pack is too low

4 FAQs about The voltage of the solar battery cabinet lithium battery pack is too low

Why is my lithium battery not charging?

Lithium batteries are reliable and long-lasting, but if your battery suddenly stops powering your gear or won't charge, it may have gone into Low Voltage Disconnect (LVD). This is a built-in safety feature controlled by the Battery Management System (BMS) to protect the battery from being over-discharged.

Can a solar panel wake up a battery in LVD?

When the battery is in LVD, solar panels often can't wake it up, especially if the charge controller needs battery power to activate. You'll need a charging source that can bypass or revive the BMS. This is the most reliable method. Connect your lithium charger directly to the battery terminals.

Why is my solar battery not holding voltage?

If your battery still won't hold voltage or shows signs of swelling or imbalance, it may need replacing. This is especially true if it's been used heavily in an off-grid solar system in Australia without regular maintenance. The BMS (Battery Management System) is what keeps everything safe. But it can also be the cause of your battery problems.

What should I look for in my lithium battery system?

Here's what to look out for in your Lithium battery system, especially when installed in remote or high-heat environments like much of Australia: Often caused by low voltage, a BMS lockout, or using an incompatible charger. Typically the result of deep discharge. The BMS cuts off output to protect the cells.
