Installation Requirements Checklist

Installing a Kora energy system involves more than just mounting the hardware. To ensure a safe, smooth, and code-compliant installation, review site requirements, clearance specifications, system sizing options from 8kWh to 28kWh, and electrical requirements before scheduling your installer.

Installing a Kora energy system involves more than just mounting the hardware. To ensure a safe, smooth, and code-compliant installation, please review the following requirements before scheduling your electrician or installer.

​

🟦 Site Requirements

1. Service Size: Kora Smart Panel is rated for 50 - 200A service. Confirm your home’s main panel and service entrance are compatible.
2. Clearance (Recommended):

• Top clearance: 12 inches (300 mm) minimum
• Side clearance (left & right): 6 inches (150 mm) minimum
• Front clearance: 24 inches (600 mm) minimum for service access
• Rear clearance (between unit and wall): 4 inches (100 mm) minimum

System size:

1. Individual Components dimensions and weight:

• Each Powerblock Battery
• Dimensions: 22.4″ (W) × 10.9″ (H) × 15″ (D)
• Weight: 81.35 lb (36.9 kg)
• Powerblock Inverter Unit
• Dimensions: 22.4″ (W) × 22.5″ (H) × 15″ (D)
• Weight: 112.4 lb (51 kg)
• Base Plate (drill mounted into the concrete slab)
• Dimensions: matches inverter footprint (22.4″ × 15″)
• Weight: 7.7 lb (3.5 kg)

8kWh Complete Stack (2 Batteries + Inverter + Base):

1. This is the minimum number of batteries per inverter
2. Total Dimensions: 22.4″ (W) × 33.4″ (H) × 15″ (D)
3. Total Weight: ≈ 283 lb (128 kg)
4. Total Energy Storage: ≈ 7.94 kWh (nominal ≈ 8 kWh)
5. Inverter Continuous Power: 11.4 kW AC output

20kWh Complete Stack (5 Batteries + Inverter + Base):

• This size maximum is required in some geographic regions
• Total Dimensions: 22.4″ (W) × 49.7″ (H) × 15″ (D)
• Total Weight: ≈ 527 lb (239 kg)
• Total Energy Storage: = 20 kWh
• Inverter Continuous Power: 11.4 kW AC output

28kWh Complete Stack (7 Batteries + Inverter + Base):

1. This is the maximum size the Kora system can currently be scaled to per stack.
2. Total Dimensions: 22.4″ (W) × 60.6″ (H) × 15″ (D)
3. Total Weight: ≈ 690 lb (313 kg)
4. Total Energy Storage: ≈ 28 kWh
5. Inverter Continuous Power: 11.4 kW AC output

Space for Panel Replacement: The Smart Panel requires the same footprint as a traditional main panel or subpanel. Verify wall space, clearance, and accessibility.

Mounting Location for Powerblocks:

• Indoor or outdoor ground-mount only(Type 4X enclosure).
• You will need a concrete slab or area of your foundation / garage to install the Powerblocks on.
• Concrete slab:
• Minimum slab capacity: ≥700 lb (≥320 kg) static load (use a safety margin above the ~690 lb weight) if installing a full 7 Powerblock tower.
• Footprint: 22.4″ × 15.0″ clear, level surface.
• Stable surface, protected from flooding or standing water.
• Adequate clearance for ventilation (follow NEC + Kora spacing guidelines).

Environmental Conditions:

• Operating temperature: –25 °C to +55 °C (with derating above 40 °C).
• Humidity: 0–100% (no condensation).
• Altitude: Up to 2000 m (6560 ft).

🟦 Electrical Requirements

• Dedicated Breaker Space: Ensure capacity in the main panel for back feeding or connecting Powerblocks.
• Grounding: Install proper earth ground in accordance with NEC and local codes.
• Neutral & Split-Phase Wiring: Powerblocks support 120/240 V split-phase. Wiring must meet local utility and AHJ requirements.
• Backup Load Configuration:
• With Kora, you do not need a separate backup subpanel.
• Backup priorities are managed digitally through the Smart Panel and Power App.

Combiner Box: If you are installing multiple Powerblocks towers you will need a combiner box. You can either buy one from Kora or your electrician can buy one from a local hardware store.

🟦 Installation Requirements

• Licensed Electrician: All installation work must be performed by a licensed electrician familiar with NEC 2023 and local jurisdiction requirements.
• Permits: Electrical and building permits may be required. Contact your local authority before scheduling installation.
• Utility Interconnection Approval: If grid-tied with solar or storage, interconnection approval is probably required from your local utility.
• Inspections: Final sign-off by the local building department, electrical inspector, or fire marshal who reviews and approves your system for safety and code compliance may be required before system activation.

🟦 Connectivity Requirements

• Internet Connection: Wi-Fi or Ethernet connection is required for the Smart Panel and Powerblocks to communicate with the Kora Power App and Energy Trading platform.
• App Access: iOS or Android smartphone required for initial system setup and ongoing monitoring.

🟦 What’s Not Needed with Kora

Unlike traditional solar + storage installations:

• No separate backup panel or subpanel— the Kora Smart Panel replaces this function.
• No manual breaker flipping during outages — backup priorities are managed automatically.

✅ In short:

Before installing, make sure you have the right service size, clear space, permits, utility approval, and internet connectivity. With these requirements met, your electrician can install Kora quickly and safely, giving you full control over your home’s energy.
