  • XTH 8000 – 48

    Bolanmu XTH multi-functional battery charger/inverter offer an optimal management of all energy sources that can be found in off-grid and hybrid systems.Once the XTH is set up in the factory, it can be plugged and played in the hands of customers.Energy flows automatically and the auxiliary contacts are configured to provide genset auto-start and alarm functions. Bolanmu XTH battery charger/inverter As an excellent energy management system provides five features:Pure sine wave off-grid inverter、Battery charger、Current inject、Transfer system and provide support to an AC source. 2 auxiliary contacts allow automatic control of a genset, the discoennection of non-priority loads or other programmable functions. These functions can be controlled in a totally automatic way for an optimal management of available energy in hybrid systems, in combination with VictorTeam MPPT solar charge controllers. battery charger Xtender inverter accessories


    1.Compatible with most battery technologies

    · like: AGM, GEL, Flooded LA NiCad, NiFE, Aquion, Redox, Lithium.

    2.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

    3.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.

    4.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.

    5.Modular design

    ·Up to 2 sets in series to increase output power. ·Up to 3 parallel to increase single-phase output power. ·3 sets in parallel can form the three-phase power supply, up to 9 sets in parallel to form the three-phase power supply。

    6.Remote monitoring function

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

    7.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.
