Solar Systems.

Grid-Tie, Hybrid, Off-Grid and Generator-integrated PV architectures — engineered around your facility's energy profile. From rooftop arrays to ground-mount plants, every system uses Tier-1 components and SANS-compliant design.

01 Grid-Tie

Grid-Tie Solar PV.

Seamlessly connected to the utility grid, grid-tie systems generate solar power during the day and automatically draw from the grid when generation is insufficient. The ideal entry-level commercial solution for businesses reducing utility bills with minimal complexity.

  • SSEG-compliant NRS 097-2-1 design and sign-off
  • Net-metering and wheeling eligible
  • LONGi, AIKO and JA Solar panel options
  • Deye inverter systems with remote monitoring included
  • Systems from 10 kWp to 5 MWp
Hybrid solar with battery storage
02 Hybrid

Hybrid Solar Systems.

E4A's flagship commercial solution. Hybrid systems combine photovoltaic generation with battery energy storage, switching automatically between solar, battery and grid to maximise energy independence, eliminate load-shedding risk and minimise peak-tariff exposure.

  • Deye inverters with Deye BOS-G HV battery modules
  • Automated load prioritisation and peak-shaving
  • Grid fallback for maximum resilience
  • Scalable battery capacity — add modules as needs grow
  • Average ROI: 3–5 years
Off-grid solar in remote setting
03 Off-Grid

Off-Grid Systems.

Complete energy independence. Off-grid systems are designed to operate entirely without utility connection — ideal for remote agricultural operations, mining sites, and facilities where grid connection is prohibitively expensive or unreliable. Engineered for continuous, uninterrupted power.

  • High-efficiency PV arrays with oversized battery banks
  • Optional generator integration and auto-start
  • Remote telemetry and performance monitoring
  • LiFePO4 battery technology — 6,000+ cycle lifespan
  • Designed for 24/7 uninterrupted supply
Solar with generator backup
04 Generator

Generator Integration.

Generators remain a critical component of energy resilience for commercial and industrial facilities. E4A integrates diesel, gas and biogas generators with solar and battery systems to create multi-source backup architectures — minimising fuel costs while guaranteeing supply continuity.

  • Seamless solar-battery-generator switching
  • Auto-start and stop logic reducing fuel burn
  • Sizing and procurement advisory
  • Integration with existing generator infrastructure
  • Remote monitoring and load management
