Battery Banks & Off-Grid Energy Storage for Coastal BC
A reliable battery bank is what keeps your lights on when the sun isn’t shining. At Kingsley Power, we design and install energy storage systems for off-grid homes, cabins, and businesses across Vancouver Island, the Gulf Islands, and remote coastal communities.
Whether you’re building a new system or upgrading an old one, we’ll help you choose the right batteries, capacity, and setup to match your energy needs and the local climate.
Our energy storage systems include:
-
- Lithium or AGM deep-cycle batteries sized to your usage and solar input
- Charge controllers for safe, efficient charging
- Battery monitors so you always know your power levels
- System design for days of autonomy based on weather and seasonal use
- Integration with solar, hydro, and backup generators
We build storage systems that last, so you can depend on them through the cloudy weeks, long winters, and real-world off-grid living.
If you'd like to schedule a consultation to discuss your off-grid solar system please give us a call (250) 228-0863 or fill out our online estimate request form and we'll get right back to you.
How to Size the Right Battery Bank
Battery banks aren’t one-size-fits-all. Your storage needs depend on how much power you use, how long you need to run without sun, and what other energy sources you have available.
Key factors we consider:
-
- Daily energy usage – How many kilowatt-hours (kWh) you need each day
- Days of autonomy – How long your system should last without sun (usually 2–4 days)
- Seasonal use – Do you use your property year-round or seasonally?
- Available solar or hydro – More generation means you may need less storage
- Backup power – A diesel generator can reduce the need for larger battery banks
We’ll walk you through all of this and design a system that fits your property, budget, and energy habits, no guesswork involved.
Lithium vs. AGM: Which Battery Type Is Right for You?
We offer both lithium and AGM deep-cycle batteries, depending on your power needs and budget.
Lithium Batteries
-
- Long lifespan (10+ years)
- High efficiency and more usable capacity
- Ideal for full-time off-grid or high-demand setups
- Higher upfront cost, better long-term value
AGM Batteries
-
- Lower upfront cost
- Maintenance-free and sealed
- Great for seasonal cabins or lighter use
- Shorter lifespan and less depth of discharge
