22-16-30 DIY Solar Kit – 22kW Off-Grid Inverter, 30kWh Battery & 16kWp Solar

A practical DIY solar kit designed for self-consumption, everyday household use, and essential backup power.
Ideal for homes looking to reduce grid reliance without oversizing the system or relying on unrealistic assumptions.

22-16-30 DIY Solar Kit

22kW Off-Grid Inverter · 30kWh Battery · 16kWp Solar

This is a full-scale off-grid power system designed for users who require very high instantaneous power and extended energy autonomy.

Built around two 11kW off-grid inverters operating in parallel, this system delivers up to 22kW of continuous power, combined with a large 30kWh lithium battery bank to support long runtimes, winter resilience, and reduced reliance on generators.

🔋 What’s included

• 36 × 450W Solar Panels (≈ 16.2kWp max)

• 2 × 11kW Off-Grid Inverters (parallel operation – 22kW total)

• 3 × 10.24kWh Lithium Batteries (30.72kWh total)

  • Integrated fire suppression

  • Integrated battery heaters for cold-weather performance

• 50 metres of PV solar cable

• DC PV Isolator

• AC Isolators

• Solar cable connectors (MC4 compatible)

Roof mounting system not included – roof type varies by installation.

✔ What this kit is ideal for

• Whole-house off-grid or near-off-grid operation

• High-load homes with multiple appliances running simultaneously

• Farms, workshops, and rural or weak-grid properties

• Electric showers (managed use)

• Heat pumps with significantly reduced generator reliance

• Sites where power continuity is critical

• Users who want maximum resilience without grid export constraints

⚠ Important design notes

• Configured as a fully islanded off-grid power system

• No grid export capability

• No DNO export approval required

• Can be paired with a generator or grid-connected charger for extreme winter conditions if required

🔋 Battery & autonomy advantages

With 30kWh of lithium storage, this system provides:

• Substantially longer runtime than smaller systems

• Improved overnight and poor-weather resilience

• Reduced generator run-time

• Greater tolerance for high-energy appliances

This is the recommended configuration for customers who want both power and endurance.

💡 Important note

Large electrical loads demand both high inverter power and sufficient stored energy.
This system is designed for users who understand that resilience comes from correct system sizing, not marketing numbers.
