Why need a case?
1.As someone who is not very familiar with electricians or wants to DIY a solar
panel pack, this DIY KITs provide you with a lot of convenience and
save time and money costs.
DIY kits include all the accessories for assembling battery pack,
such as epoxy boards, busbars(including the crossing busbar),
BMS,Active balancer, cables and screws, etc.
No need to go to tens of shops to purchase those accessories.
2.According to the installation video or manual, a person with no technical
knowledge can probably assemble it in 3-4 hours. A skilled person
can assemble it in 1-2 hours. Greatly saving labor.
3.DIY kits and battery cells are priced lower than completed battery packs,
and shipping costs are also cheaper,because there will be
overweight charges for the battery pack.
4.The case supplies external mechanical pressure
- Resistance to vibration and impact
Continuous vibration is generated during the operation of
vehicles/equipment, and fixed structures (end plates, brackets,
straps) are used to prevent battery cell displacement, collision,
resulting in shell rupture or pole loosening.
- Inhibit the cumulative effect of inflation
Although the expansion of individual cells is small, the slight
expansion and superposition of hundreds of cells after grouping may
squeeze the box. The fixing system can disperse stress and avoid
deformation of the box.
- Ensure consistent heat dissipation
By using fixtures or thermal conductive structural adhesives, the
large surface of the battery cell is tightly adhered to the cooling
plate, improving thermal management efficiency (insufficient heat
dissipation can lead to uncontrolled heating).
- Maintain the reliability of electrical connections
Prevent the pole from loosening due to vibration and avoid local
overheating caused by virtual connection of connecting pieces.
Suitable for home energy storage, 48V 15-18KWh Off Grid&Hybird
Grid System.
During the day, batteries store solar energy or store Grid
electricity when it is cheaper, and use the battery's power at
night and during peak hours.
What is the difference to V3
1.There is a 250A DC Breaker on V4 kits
When overload or short circuit faults
occur in the DC circuit, the DC circuit breaker can quickly cut off
the circuit, prevent equipment overheating or damage, avoid arc and
fire risks, and protect the combiner box and downstream equipment.
When repairing or replacing equipment, manually disconnecting the
circuit breaker can cut off the current and ensure personnel
safety. In addition, circuit breakers can isolate faulty components
and prevent the entire system from shutting down.
2.Touch screen,multiple language
Colorful touch screen,indicating voltage,current,SOC.able to select
protocal of inverter.
3.20% smaller
Space saving when multiple packs in parallel
