FAQ
Frequently Asked Questions (FAQ)
Q1: What inverters are compatible with the BPE-HV-PRO High Voltage Battery System?
A: Our system is engineered with a widely compatible BMS that supports CAN and RS485 communication protocols. It is fully compatible with leading high-voltage hybrid inverters including Deye, Sol-Ark, Growatt, Megarevo, GoodWe, and Victron. For specific protocol matching or other brands, please contact our engineering team for confirmation.
Q2: Why choose a High Voltage (HV) battery over a traditional 48V Low Voltage system?
A: High Voltage systems (200V-400V+) offer superior efficiency for large energy demands. Unlike 48V systems, HV batteries operate with lower current, which means less heat generation and energy loss. This allows for the use of thinner cables and ensures higher conversion rates, making them ideal for powering heavy loads like central air conditioning, heat pumps, and commercial machinery.
Q3: Is the BPE-HV-PRO system scalable for commercial applications?
A: Absolutely. The modular “stacked” design allows you to start with a single cluster (e.g., 20kWh) and expand as needed. You can connect multiple stacks in parallel to achieve a total capacity of up to 204.8kWh. This flexibility makes it perfect for expanding from large residential setups to commercial energy storage (C&I) projects.
Q4: What is the cycle life and warranty of these LiFePO4 battery modules?
A: We use Grade A Lithium Iron Phosphate (LiFePO4) cells, known for their safety and longevity. The BPE-HV-PRO series is rated for 6,000+ cycles at 80% DOD (Depth of Discharge), which translates to a design life of over 10-15 years. We offer a standard 5-year warranty, with options to extend for long-term commercial partners.
Q5: Is the installation complicated? Do I need special wiring?
A: No, installation is one of the key advantages of this product. It features a wireless stacking design. The modules plug directly into each other without internal cable clutter, significantly reducing installation time and labor costs. The “Plug & Play” nature minimizes the risk of wiring errors on site.
Q6: Do you offer OEM/ODM services for this battery system?
A: Yes, as a direct battery manufacturer, Balder Power specializes in OEM/ODM solutions. We can customize the exterior housing color, logo branding, and even software protocols to match your local market needs. We welcome inquiries from distributors and installers worldwide.
