Emaldo Power Core User Manual
When the internal temperature of the battery module is low, the internal heating
component starts to heat the battery. During the operation of the heating component, the
heating power and the charging power are roughly equal, and the battery is not charged,
with no change in SOC. Heating the battery is beneficial for maintaining the battery cell at
a suitable operating temperature and prolonging the service life of the product.
• Is it better to place photovoltaic modules vertically or horizontally?
Horizontally.
• Will wiring AC cable and communication cable together in the energy storage system
affect communication quality?
Wiring AC cable and communication cable together in the energy storage system will
affect the communication quality, as the AC output from the AC cable generates a strong
magnetic field due to the high current, which will have an effect on communication. Thus,
generally, communication lines will be shielded and provided with certain isolation
measures.
• The energy storage system has the low insulation impedance alarm. How to troubleshoot
it?
Turn off the energy storage system first, and then turn off all circuit breakers of the
Additional Cabinet, and use a multimeter to test over the ground. If no problems are
detected, a megger meter is used for measurement. Check the DC wiring to see if there is
DC short circuit over the ground.
• Can different MPPT of the energy storage system be connected with different components?
Yes.
• What does output overcurrent protection of the energy storage system mean?
In the event of a sudden voltage jump or short circuit in the power grid, the output current
of the energy storage system will sharply increase. To protect internal components from
damage, the energy storage system will provide output overcurrent protection.
• What is anti-islanding protection?
If the power grid is disconnected, the energy storage system may continue to operate with
the local load, forming an island and posing a safety hazard. According to grid connection
standards, it is required that the energy storage system shall shut down its output within
the specified time.
