Professional installation: The definitive guide

🔧 Pre-installation checklist

☐ Verify inverter compatibility (table above)
☐ Calculate number of modules needed
☐ Plan appropriate cable lengths
☐ Prepare 19-inch rack cabinet
☐ Install ventilation system if > 10 modules

📋 DYNESS installation procedure

Step 1: Initial configuration

Configure the DIP switches of each DYNESS B4850 module according to your inverter BEFORE powering on. This is critical for automatic recognition.

Step 2: Modular connection

Start by connecting 2 modules with 50cm cables. Test BMS communication before adding other modules. This progressive approach avoids costly errors.

Step 3: Progressive expansion

Add modules one by one, checking balance after each addition. The DYNESS BMS automatically manages addressing up to 40 modules.

Step 4: Advanced monitoring

Configure monitoring via Victron VRM, SolarAssistant or Home Assistant. Real-time monitoring is essential for installations > 20 kWh.

❓ Advanced technical FAQ DYNESS B4850

🔋 What is the optimal depth of discharge (DoD)?

Answer: The B4850 supports 90% DoD while guaranteeing 6000+ cycles. To maximize lifespan, an 80% DoD allows reaching 8000 cycles.

🌡️ Thermal management for installations > 50 kWh?

Answer: Beyond 20 modules, active ventilation is recommended. The BMS automatically limits power if T > 45°C. Allow 10cm space between racks.

⚡ Can B4850 be mixed with other DYNESS series?

Answer: Yes, compatible with B3 and Tower series, but in separate groups. Never mix different capacities in the same parallel string.

🔌 Maximum distance between modules with 2m cables?

Answer: Resistance remains < 1mΩ up to 2m. Beyond that, plan for a 35mm² cross-section or use bus bars for MW installations.
