Meet the power consumption of different houses
How to connect batteries with the inverter and MPPT
1. 3% power over specification
A+++ cells, buying 100Ah,you get 103Ah
2. Internal protection
ABS holder higher than bus bar Against shock/heavy drop above the metal lids.
3. Comprehensive monitoring
4 temperature sensors and 16 voltage sensor Each cell is under control by BMS
4. Double strong connection
Double strong connection Busbar is connected by screws and laser welding, double insurance
5. Read battery infomation on the computer
With RJ45 wires ,you can read battery info on the computer via RS485 Information includes cell voltage, total voltage, cell temperature, SOC, and so on
| CTS | Other |
Plastic holder | 1.We use customized plastic holder between each cells for better insulation, so when the operator install batteries, there will be no danger | No holder between cell, insulation need to be concerned |
Top extension | 2.There is an extension at the top of the bracket. When there is a shock or heavy drop or vibration, battery itself will not be the first to bear the brunt | Have a metal top extension in the first one, no top extension in the second |
Unblocked explosion-proof valve | 3.The explosion-proof valve is not blocked, the physical structure safety of the cell is ensured | Both has blocked explosion-proof valve, not meet the cell safety using requirements |
BMS with cover | 4.BMS is well protected by metal cover, prevent damage for shock | No cover on both BMS |
Laser welding+Screws | 5. We use laser welding around the srew to further strengthen the connection to completely eliminate the risk of screw falling. Laser welding also reduce the contact surface between the screw and the bus bar to enhance current capability. This laser welding can also reduce internal resistance and reduce power consumpution. The user can get more power | First has untidy welding, big risk of damage cables, second only srews. |
Orderly cable arrangement | 6. Orderly cable arrangement can reduce poor connector contact, short circuit and open circuit between wires | lack of standardization, cables go through basbar in the first, disorder cables in the second |
