Frequently Asked Questions (Q&A)

Q1: What is the Deye BOS-W 5.12 kWh module? A: It is a high-voltage LiFePO₄ battery module used as the building block for Deye BOS-W energy storage systems. Multiple modules are connected in series with a control box (PDU) to form larger high-voltage battery banks.

Q2: How many modules do I need? A: Minimum recommended is 5 modules (25.6 kWh). You can scale up to 17 modules (87 kWh) depending on your inverter and energy requirements.

Q3: Does it work with Deye hybrid inverters? A: Yes. It is designed for seamless communication with compatible Deye high-voltage hybrid inverters via CAN or RS485.

Q4: Is this a low-voltage or high-voltage battery? A: It is a high-voltage system module. Each module is 51.2 V, but they are connected in series to create a high-voltage battery bank (typically 200–900+ V).

Q5: Can I expand the system later? A: Yes. Additional modules can be added within the supported range as your energy needs grow.

Q6: Do you deliver and install in coastal towns? A: Yes. We actively serve Mombasa, Malindi, Kilifi, Diani, Watamu, Mtwapa, Lamu, Kwale and other coastal areas, plus Nairobi and nationwide delivery.

Q7: What else do I need besides the battery modules? A: You will need the matching Deye high-voltage control box (PDU), communication & power cables, and a suitable rack. We supply complete matched systems.

Q8: Is professional installation required? A: Yes. High-voltage battery systems must be installed by qualified technicians for safety and to maintain warranty validity.

Q9: What is the expected lifespan? A: ≥6,000 cycles under recommended conditions — typically 10+ years of daily use.

Q10: How can I get a quote or system design? A: Call or WhatsApp +254 716 842 775. Share your location (especially if coastal) and approximate daily energy needs, and we will design a suitable BOS-W system for you.
