Off Grid Solar Batteries
Solar batteries are the heart of an off grid solar power system. It is there for you when the sun goes down, and is essentially the storage place for all the sunshine you collected during the day. A properly designed solar battery bank will give you years of service, while a poorly-sized battery bank will only offer years of frustration. You should get more than 10 years out of a properly sized solar battery bank.
Solarwyse strives to offer our customers the best selection of batteries available, at fair pricing. Please take your time to read about the various technologies and call us if you have any questions.
Due to the increase in the price of lead on the world market expect an industry wide increase in battery prices, ie the MSRP for the Surrette s-550 will increase from $397 to $461. We have a limited supply at $365 in lots of 12. Increase effective April 1, 2017.
FLOODED LEAD ACID
Our line of flooded lead acid batteries is manufactured in Spring Hill, Nova Scotia, and is becoming one of the leading standards in off grid solar installations. You will find them installed all over the globe.
This big red series of batteries is commonly found in most solar power systems in Canada, and the United States under the name of Rolls.
All lead acid flooded batteries must be enclosed and vented to the outside, as they will produce explosive gasses when charging.
- Least Expensive
- Can be equalized
- Require monthly maintenance
- Must be vented outside
- Posts corrode as batteries age
- Life span 10+ years
The AGM “Absorbed Glass Mat” batteries are our best sellers. The technology incorporated in these batteries allows manufacturers to increase their warranty by two years over that of the flood battery. These batteries are sealed and can be installed indoors. They can also be installed in any position, even laying on their sides.
Our line includes Canadian-made Surrette and the popular US-made Power Sonic. We are always looking for quality batteries to offer our clients.
- Sealed spill proof design
- Maintenance free
- Can be mounted on their sides
- Mid range pricing
- Can not be equalized
- Heavier based on storage capacity
- Life span 15+ years
Lithium Iron Phosphate
Lithium Iron Phosphate batteries are hottest technology on today’s market, made famous by TESLA Motors. These leading-edge batteries have overcome the charge density issues present in other battery technologies, and will fully recharge in lower ambient light conditions. However, lithium batteries require an additional computerized battery management system.
Clients considering geo-thermal system would find enhanced system performance with a bank of properly sized lithium batteries.
- No need to equalize
- Highest charge density
- Last 15 to 20 years
- Highest pricing
- Requires additional battery management
Aqueous Hybrid Ion (AHI™)
This salt-water battery features the latest technology in battery design, and is by far the most environmentally safe. No caustic acids, only salty water, carbon and a few other non-toxic elements. More information on the Aquion Energy website.
The number of lifetime cycles far surpass that of the flooded battery technology, and at least equal to the Lithium.
- Very high cycle life
- Usable depth of discharge (DoD): 100%
- Ability to stand at partial state of charge
- Wide operating temperature range
- High efficiency
- Equalization not required
- Higher costs
- Only available 24 and 48 volt banks
