Is necessary to pay for a DIY kit of 48V home solar?
The kit includes all the core components required for assembly, eliminating the need to purchase them one by one from different stores.
The main components such as BMS have pre reserved positions and hole positions, avoiding a lot of messy manual soldering and wiring, greatly reducing the error rate.
Most kits adopt a plug-in design that does not require soldering. Ordinary people can assemble them within 1-4 hours according to the video or instructions.
The time saved for searching, comparing, communicating, and reworking is itself a huge hidden wealth.
The BMS integrated into the kit is the "brain" of the battery, providing comprehensive protection such as overcharging, overdischarging, short circuit, overcurrent, and temperature control.
2A active balancing is crucial for battery consistency and long-term use
The dedicated battery box can provide mechanical protection against earthquakes and impacts, and ensure effective heat dissipation through fixtures or thermal conductive adhesive to prevent danger caused by overheating.
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.
2A Active balancer module
Active balancer module has been installed.
Balance starts when the voltage difference higher than 50mV.
Balance stops when the voltage difference lower than 30mV.
Balance starts and keep for 60s, then it will stop for 3s to check if the voltage gets balance start/stop threshold.
After continuously balance for 24H, Balance will stop.
Balance board will turned off automatically if no balance for over 10 hours.
Power consumption less than 15mA at standby status.
CAN,RS485
Support various brand inverter with CAN protocal,including pylontech. BMS still workable with lead acid mode if you don't use CAN or 485.
