Have questions? You’re not alone.

We’ve gathered some of the most commonly asked questions about our services, processes, and support to help you find answers quickly and easily. 

When wiring a small system, please take note of the following:

  1. Follow the markings on the bracket when connecting the silicon chain conversion section.
  2. Connect the batteries according to the user manual.
  3. Do not overload the fault output section of the bracket — the maximum load it can support is 12A at 250VAC or 12A at 30VDC.
  4. The rated conventional load on the control bus of the small system is 12A.

The designed maximum battery capacity for our large system is 2400Ah.

Yes, please observe the following precautions:

  1. Do not reverse the polarity when connecting module outputs to battery terminals.
  2. Do not connect communication ports in reverse or link them to unrelated circuits.
  3. Ensure the module’s environment meets specified operating conditions.
  4. Keep ventilation clear to ensure proper heat dissipation.

Our modules are equipped with the following features:

  1. Automatic current sharing
  2. Hot-swappable design
  3. Built-in LCD display for monitoring
  4. Anti-reverse diode protection
  5. Fault status indicators
  6. Comprehensive self-protection
  7. Full digital communication control
  8. All components are sourced from reputable, certified suppliers

We offer different configuration plans based on your power requirements:

 

A. Small System (≤220V/65Ah or ≤110V/100Ah):

 

To reduce production costs, we recommend a small system, which includes:

  • 1 Small System Controller
  • 1 Small System Bracket
  • 3 Rectifier Modules

 

B. Large System (>220V/65Ah or >110V/100Ah):

 

To ensure design redundancy and achieve N+1 backup, we recommend a large system. Configuration depends on battery capacity and load, but typically includes:

  • Main Controller
  • AC Monitoring Unit
  • DC Monitoring Unit
  • Switch Signal Monitoring Unit
  • Rectifier Modules
  • Bracket

 

Optional Add-ons:

  • Insulation Monitoring: Two 60-channel insulation inspection units
  • Battery Inspection: Options for 18-cell or 108-cell battery inspection units

 

C. Available Monitoring Devices:

  1. Small System Controller
  2. Large System LCD Controller
  3. Large System Touchscreen Controller

 

D. Available Rectifier Modules:

  1. 5A / 220V AC/DC (air-cooled)
  2. 7A / 220V AC/DC (air-cooled)
  3. 10A / 110V AC/DC (air-cooled)
  4. 10A / 220V AC/DC (air-cooled)
  5. 15A / 110V AC/DC (air-cooled)
  6. 20A / 220V AC/DC (air-cooled)
  7. 10A / 220V AC/DC (self-cooled)
  8. 20A / 110V AC/DC (self-cooled)

 

E. Available Monitoring Units:

  1. AC Monitoring Unit
  2. DC Monitoring Unit
  3. Switch Signal Monitoring Unit
  4. Battery Monitoring Unit
  5. Insulation Monitoring Unit

ments:

Check the following:

  1. Whether the system monitoring wiring sequence is correct — the main power should be turned on before the control circuit.
  2. If the band switch setting on the monitor is configured correctly.
  3. Whether the sensor’s cable direction is properly aligned.

To simplify installation and commissioning, our bracket is designed as an integrated unit. The customer only needs to connect:

  • Three-phase input
  • Two-phase output

 

The internal silicon chain connects directly to the control bus — we call this full integration.

 

If the customer’s design requires:

  • Two modules supplying power solely to the control bus,
  • And the other modules connected to the main bus,

 

Then we provide a bracket with two additional power supply wires for the control bus. This is known as separate control integration.

Our main controller supports both RS232 and RS485. Users can select the mode by adjusting a DIP switch based on the included instructions.

  • Small systems default to RS232.
  • If RS485 is required, a converter module is needed.

Yes. All of our modules use hardware-based automatic current sharing.

We pre-connect the current sharing lines at the back of each bracket.

If current sharing is required across multiple bracket levels, we also provide external current sharing connections ready for use after installation.

Yes, our large system supports dual battery group and dual bus management.

However, both battery groups must have equal capacity.
