Off Grid Solar – Battery Storage
Introducing Off Grid Batteries
SolarKing are proud to offer two different types of off grid solar batteries with our Larger Off Grid Solar packages.
We offer Lead Carbon batteries and AGM Batteries which both perform exceptionally well and come with strong battery warranties. The different battery options suit different usage options and budgets, with the Lead Carbon batteries being slightly more expensive.
To help answer your questions about which is the best battery option for your Off Grid Solar needs we’ve put together a video answering frequently asked battery questions. We have also provided an overview of both battery types below for your reference summarising the battery performance and key information to know.
Should you have any questions about which battery would best suit your needs, simply call the friendly team at SolarKing on 0508 Solar NZ (0508 765 276) or click the button below – we’re here to offer no obligation help and advice.
Which battery option is best for my needs?
AGM Batteries
When you need a long lasting battery that can withstand harsh weather conditions, Absorbent Glass Mat (AGM) deep cycle batteries are your best choice.
With their absorbed glass mat technology containing the acid, AGM batteries are 100% sealed, non-gassing, and maintenance free.
AGM batteries will never leak acid, even if they are damaged.
Designed for deep cycle applications, frequently charging and discharging does not harm them, making them ideal for off grid battery storage solutions.
Where to use AGM batteries:
- Small to medium off grid systems
- Applications with medium service lives
- Projects with budget conscious design
- Strict space confines
Key Performance notes for AGM Batteries:
Lead Carbon Batteries
With a superior service life of up to 20 years, lead carbon batteries are some of the best batteries available projects that require reliable and long lasting batteries. A lead carbon battery is a new type of battery where supercapacitor technology is used to prolong the life of the battery unit.
Just like the AGM deep cycle batteries, lead carbon batteries are protected against leakage, even if the battery is broken.
Lead carbon batteries have lower freezing and higher boiling points than batteries with liquid electrolytes, making them suitable for usage in extreme environmental conditions.
Where to use Carbon batteries
- Applications with long service lives
- Setups requiring high reliability
- Superior safety performance required
- Communication equipment and UPS

AGM verses Lead Carbon Battteries – Which one wins?
Which battery type wins?
It’s a question many of you have asked us recently.
SolarKing offers two distinct Large Off Grid system options, identical in every way except for the battery type.
To clarify the differences between the batteries, we have created this brief overview highlighting the main points.
There is clearly some buzz in the market regarding Lithium type batteries, and although there are many different versions, we have included a general Lithium option in this overview:
To summarise, you can see that the Carbon option provides significant advantages over AGM, however there is quite a significant extra cost for the Lead Carbon option at nearly twice the price.
Offsetting this is the extended life of the Lead Carbon batteries, with a design life of 20 years for nearly twice the price of AGM with a design life of 12 years.
Many clients are opting for AGM batteries with a view to upgrade to new technology storage solutions, in due course, within the AGM battery lifetime.
