Battery Wall Base for 6.6kWh Stackable Lithium Battery SPHI-B-6.6WB
The SimpliPHI 6.6 kWh Battery (Model: SPHI-B-6.6WB) offers flexible installation options, including both wall-mounted and floor-standing configurations.
Wall-Mounted Installation:
Mounting Bracket: For wall installations, a suitable mounting bracket is required to securely attach the battery to the wall. This bracket ensures the battery's weight is properly supported and maintains safety standards.
Wall Requirements: The wall must be structurally capable of supporting the battery's weight, which is approximately 140 lbs (63.3 kg). It's essential to assess the wall's load-bearing capacity and use appropriate anchors or supports as specified in the installation manual.
Floor-Standing Installation:
Ground Base: If opting for a floor-standing setup, the battery can be installed using a ground base designed to accommodate up to three stacked batteries. This base provides stability and ensures proper alignment of the units.
Dimensions of Ground Base:
- Width: 28.6 inches (726.4 mm)
- Depth: 6.7 inches (170.9 mm)
- Height with Tabs: 3.5 inches (88.9 mm)
- Height without Tabs: 1.9 inches (48.3 mm)
Installation Considerations:
Indoor and Outdoor Use: The SimpliPHI 6.6 Battery is rated for both indoor and outdoor installations, offering versatility in placement. Ensure the installation environment meets the operational temperature and humidity ranges specified in the product datasheet.
Stacking Capability: The battery design allows for stacking up to three units, either on the ground base or wall-mounted, to increase energy storage capacity. Proper stacking hardware and alignment are crucial for safety and performance.
