3.5Kw 5KWh Residential Energy Storage System


Bolanmu YTM-4000 5KWh 100Ah LiFePO4 Residential Energy Storage System  with hybrid inverter is a fully-integrated home energy storage system with 5kWh or 10kWh LiFePo4 batteries, hybrid inverters compatible with any type of AC power and easily retrofitted into existing solar PV installations. The system has 2 auxiliary contacts that can be set up to store energy generated during the day, And discharge it at night when domestic demand peaks. We expect the battery pack to last about 15 years with more than 3,000 cycles.

Transfer Switch(UPS、Back up power)

·0 ms transfer time when switching from Inverter to AC input source
·<0.15 ms transfer time when switching from Inverter to AC input source

Surge Capacity (inductive load)

·The inverter has a surge capability of 3X its continuous power rating.
·The inverter load can exceed the continuous output power for up to 30 minutes, allowing a power boost without triggering and overload failures.
·There is no need to choose more powerful inverters because of the excess load of a little time, which will greatly reduce the cost.

Ac input

·Can access 2 kinds of AC power supply, and the two kinds of AC power supply for programming.
·Compatible with any kind of AC source.
·6 stages battery charging:
·Bulk-Absorption-Floating-Equalization-reduced-floating-periodic absorption
·Solar priority or battery priority can be set.

Remote monitoring function

·Local monitoring and data acquisition through RCC.
·Monitoring system through mobile APP SmartEss.
·Monitor the system through the Web side.

Electronic protection functions

·Deep discharge protection.
·Battery overvoltage shutdown .
·Short circuit protection.
·Overtemperature and overload protection.
·Reverse polarity protection by internal fuse(except XTH3000).
·Acoustic alarm at deep discharge or overheating.
