Pallet Lot: 5x SolaX Triple Power 5.8kWh HV LiFePO4 Solar Batteries (2x T-BAT H 5.8 Master + 3x HV11550 Slave) - AS-IS for Parts/Repair/Repurpose

For sale is a full pallet of 5 SolaX Triple Power high-voltage lithium (LiFePO4) solar battery modules – total nominal capacity 29kWh when functional. These are genuine SolaX units manufactured by SolaX Power Network Technology (Zhejiang) Co., Ltd. Overall this lot seems to be a mix of either unused or rejected units. They are super clean. Of course they are still in the original boxes but some accessories are missing from a couple of boxes.

Breakdown of units included:

• 2x T-BAT H 5.8 (Master versions with integrated BMS, heater, and full electronics)
• 3x HV11550 (Slave / extension modules, model often labeled T-BAT H 5.8 Slave)

Condition: Sold strictly AS-IS, NO RETURNS – for repair, parts, DIY projects, or repurposing

We tested the external terminals and measured 0V / no voltage on every unit. This is common with new SolaX Triple Power batteries because:

• The BMS (Battery Management System) is in sleep/shipping mode and requires proper activation/wakeup via a SolaX hybrid inverter (or specific commissioning procedure).
• Or the packs may have self-discharged into deep sleep / over-discharge protection during long-term storage.

These are NOT guaranteed to charge or function. Some buyers successfully wake these up with the correct SolaX inverter or BMS reset procedure; others may need cell balancing, BMS replacement, or may have deeper issues. We are selling them strictly “as-is” with no testing beyond confirming zero external voltage and visual inspection (no damage, no swelling, no leaks).

Huge value in components and materials even if cells are unusable:

• High-quality IP55 weatherproof metal enclosures – perfect for custom battery builds, off-grid projects, or repurposing as tool/storage cabinets (retail value alone ~$300–$500 each).
• Full BMS & control boards in the two Master units (advanced SolaX BMS with CAN/RS485 comms, contactors, pre-charge circuits, heating elements – easily worth $800+ each if harvested).
• High-quality circuit boards, contactors, fuses, shunt, wiring harnesses, aviation-style power connectors, RS485/CAN cables, etc. inside every unit.
• LiFePO4 prismatic cells (if recoverable – 50Ah @ ~115V nominal, Grade-A cells from top-tier supplier). Even if some cells are low, many DIY builders salvage 80-100% capacity.
• All accessories included where present (communication cables, power link cables, wall-mount brackets, etc.).

Normal retail price for these units when new and working:

• T-BAT H 5.8 Master ≈ $2,800–$3,500 each
• HV11550 Slave ≈ $2,200–$2,800 each Total new retail > $13,000–$16,000

Perfect for:

• Solar installers who already own SolaX inverters and know the wakeup procedure
• DIY Powerwall / off-grid builders
• LiFePO4 cell harvesters
• Anyone wanting premium IP55 enclosures + high-end BMS boards
