Off-Grid System Upgrade Case Study
From Lead-Acid Limitations to High-Performance Lithium Storage
A recent project where we upgraded a 12-year-old off-grid system to improve reliability, storage, and year-round performance.
The Challenge
12-year-old system
Lead acid batteries (limited lifespan, lower efficiency)
Under-sized solar array
The Upgrade
Doubled storage capacity
Installed Discover Helios Lithium Batteries
Increased solar array by 200%
Bottom row optimized for winter performance
Before the upgrade, during our on-site evaluation of the off-grid system. Solar panels covered in snow highlight real winter conditions and the seasonal performance challenges we design for in Ontario.
Before the upgrade, captured during our on-site evaluation. This view highlights how winter conditions and system layout influenced performance, guiding the design of the upgraded off-grid solution.
During the installation phase of the off-grid system upgrade. Our team prepared the ground-mounted structure and panel layout to support increased solar production and long-term reliability.
Our team installing the 500 Watt Longi solar panels on the main roof-mounted array. The 500 Watts Longi panels are replacing the older 235 Watt solar panels to more than double the solar capacity.
After completing the main roof section of the array, our team installed the vertical panels which will be turned on in late fall to take advantage of the lower sun and snow reflection for increased power output.
Our licensed electrician connected the inverter generator and battery system together. Transitioning from lead-acid to lithium storage will reduce generator run-time by 50%. This will result in fuel savings and maintenance on the generator.
The result
Improved system reliability in all seasons
Increased energy storage capacity
Optimized solar production throughout the year
Reduced maintenance and fuel cost compared to lead-acid systems
Who This Upgrade Is For
Homeowners with older off-grid systems
Systems using lead-acid batteries
Properties experiencing winter performance limitations
Anyone looking to increase energy independence
