Battery use precautions
The Wall-Mounted Solar Home Battery is composed of a battery pack and a control system.
Non-professionals and improper operation and use may cause serious consequences such as
sparking and short circuit. The installation and maintenance of the system must be performed
by professional technicians, and the use must strictly comply with the relevant safety
regulations. Non-professionals are strictly prohibited from installing, repairing, and
over-discriminating lithium battery packs.
1. Please read this manual and keep it in a safe place.
2. Please pay attention to all warning signs on the battery, do not tear or damage the
warning labels.
3. Do NOT immerse the battery in sea water or water. When it is not in use, keep it in a cool
and dry place.
4. Do NOT use or leave the battery near hot high temperature source, such as fire, heater,
etc. Do NOT expose the lithium battery to fire, the lithium battery may explode.
5. Please charge it with the special charger for lithium battery. Do NOT plug the battery
directly into the power socket.
6. Do NOT directly connect positive and negative terminals of the battery with metal.
7. Do NOT knock or throw the battery, step on the battery or directly solder the battery and
pierce the battery with nails or other sharp objects.
Precautions
• Do not use or place the battery at high temperature, as this may cause the battery to
overheat, ignite or fail, and shorten its life.
• Do not use in places with strong static electricity and strong magnetic field, otherwise it
will easily damage the battery safety protection device and bring unsafe hidden dangers.
• If the battery leaks, the electrolyte enters the eyes, please do not rub it, rinse your eyes
with clean water, and immediately send to medical treatment, otherwise it will hurt your
eyes.
• If the battery emits an odor, get heat, discoloration or deformation, or any abnormality
during use, storage, or charging, immediately remove the battery from the device or
charger and stop using it.
• If the electrode is dirty, wipe it off with a dry cloth before use. Failure to do so may result in
poor contact failure.
• Cover the electrode with insulating paper before discard the battery, to prevent fire
caused by accidental short-circuit.
Keep the product well ventilated.

2.4.1 Voltage Protection
Low Voltage Protection in Discharge
When discharging, the protection will turn on if the battery or any single cell has lower voltage,
and the battery will stop discharging. When battery voltage or all single cells voltage are back
to normal, protection will be removed.

High Voltage Protection in Charge
When charging, the protection will turn on if the battery or any single cell has high voltage, and
the battery will stop charging. When battery voltage and all single cells voltage are back to
normal, protection will be removed.
Voltage protection parameters please see "Table 2-2 Protection Parameters".
2.4.2 Current Protection
Over-current Protection in Charge
If the charging current is higher than the protection value, the battery will stop charging. As
current back to normal, protection will be removed after the delay time.
Over-current Protection in Discharge
When the discharge current is higher than the protection value, the battery will stop
discharging. Protection will be removed after the delay time. Protection parameters please see
"Table 2-2 Protection Parameters".
Charging/Discharging Current Limit
To ensure the load product working safety, V+ solar home battery sets the maximum
charge/discharge current protection values. Please see "Table 2-2 Protection Parameters".
In product working, the maximum operating current of electrical load should be less than the
maximum battery discharge current.
2.4.3 Temperature Protection
Charging/Discharging Temperature Protection
Operation temperature of battery is 65℃, when temperature is above 65℃, protection will turn
on and cut off power.
2.4.4 Additional Protection Features
Short Circuit Protection
