Solar Electric System Batteries

Batteries in solar applications need to be able to meet the demands of unstable power from the grid, heavy charging cycles and irregular full charging. This requires a special type of battery to be able to handle these difficult tasks. Our range of top quality solar batteries are designed to meet these requirements and provide a reliable service for an extended life, with minimal maintenance.

Solar Electric System Batteries

Solar Batteries

Deep cycle Batteries are designed to store energy for when it is required i.e. during times of little or no solar generation or high energy demand. There are various battery technologies available for different applications and so it is important to choose the correct technology for your requirements.

Off Grid Batteries

Off grid batteries need to store a large amount of energy, so that there is plenty of energy available during extended bad weather. If the battery is undersized, it will be discharged to a lower state of charge more regularly and therefore shorten the life expectancy. You will also be more reliant on a back up source of energy like a generator, to top up the system more often.

Common battery technology used for off grid systems are Lead Acid i.e. Enersun and Lead Carbon i.e. Shoto

Grid Connected (Hybrid) Batteries

Grid connected (Hybrid) batteries are designed to retain the solar energy you generate on site, rather the sell it to the grid and buy it back later at a much higher rate. A grid connected home would ideally be designed so that appliances run during sunshine hours where possible, directly from the solar system. Batteries can then be add to store the remaining solar energy for use during the evening, high demand or low generation times. Unlike off grid batteries, you only need to store a small amount of energy to cover the evening usage, however if you fall short the grid will continue to support your energy demand as usual.

Common battery technologies used for grid connected (Hybrid) systems are Lithium Iron i.e. LG Chem, Enphase, Tesla Powerwall

Enersun
Enersun Solar Energy Batteries are specifically designed and manufactured in Australia to provide DC power for Remote Area Power Systems (RAPS) in the harsh conditions. Advanced Technology tubular positive plate construction has ensured the long service life of these batteries, estimated to last in excess of 12-15 years in a correctly sized and maintained solar system. The SSR range consists of individual 2 volt cells encased in a rugged steel case.

Features:
  • Advanced technology tubular positive plate construction - ideal for deep cycling applications
  • Large ‘top of plate’ electrolyte reservoir to minimise topping up for less maintenance
  • Large volume electrolyte minimises effect of temperature variation
  • High charge acceptance - ideal for solar applications
  • Robust construction and heavy duty casing designed to last as long as the battery
  • Detailed installation and maintenance manual provided with each battery
  • Maintenance kit, including hydrometer and thermometer, provided with each system
  • Wraparound separators provide extra protection against short circuits.
WARRANTY – The Enersun SSR range is warranted against defects in material and workmanship for a period of three years from the date of installation.

Crown
Nobody builds them like Crown. No one else invests in the heaviest, thickest plates in the industry. Crowns plates are over 10% thicker than their competitors. Combine that with their proprietary PROeye™ and low-maintenance container – features that make battery maintenance predictable and efficient – and you’ve got a battery that’s going to last longer and perform like no other.

Features:
  • Heat-sealed Case and Cover Design
  • Rigid Connectors - Heavy-duty TTP, COS and Post connectors deliver maximum electrical efficiency and durability
  • X-TEND Container Design - X-Tend provides more electrolyte above the battery plates so batteries can perform longer between watering intervals, lowering preventive maintenance costs and improving overall ROI on your Crown Battery purchase
  • Heavy-Duty Construction - Crown deep cycle batteries are the heavyweight of the industry. More weight means more lead, which translates into a battery that will work and last longer.
  • PROeye™ - No mess, no guess system for inspecting electrolyte levels that signals when watering is required
  • Posi-Wrap™ Envelope Separators - Posi-Wrap Separators reduce maintenance and prevent failure due to short-circuiting and plate shredding, ensuring reliability and durability
  • Z3 Plate Construction - Crown’s Z3 design combines three integrated features for superior performance and durability
  • Our signature “Diamond Z” grid architecture
  • An inset lug position
  • Our revolutionary “LifePlus™” active paste material.
