Integrated Power Cabinets
​
Off-Grid Solar Energy Storage Cabinets
Saltwater Solar provides complete off-grid power system cabinets containing batteries and all enabling equipment for continuous electricity supply to remote area homes, businesses and remote communities.
​​
​Features
Meets all Australian Standards for Remote Area Solar Systems, including the stringent requirements of the new AS-5139 battery standard.
-
Cabinets are built and tested in our Darwin workshop to complete technical integration before they travel, to avoid painful commissioning issues on site.
-
Delivered and placed by truck crane in suitable shed or under the eaves of an existing building, or on dedicated concrete pad or galvanized posts. Keeping onsite work to a minimum.
-
Community Power Packs are connected to the Solar Array, Main Switch Board and Backup Generator, as well as the household energy management systems.
-
We have integrated proven Australian made batteries, battery inverters, and solar regulators to ensure these systems are the most rugged available, with the best backup service and long warranties.
-
User friendly remote monitoring and networked energy management to keep the lights and fans on even during monsoons.

Design Priorities considered
-
The lowest possible Levelized Cost of Electricity (LCOE) – or lifetime cost per kilowatthour. We work on the basis of an average 15 year life for the whole system, as this is realistic and achievable. Components may last much longer, but usage patterns may also change over this period, requiring further upgrades.
-
Oversize the solar array (up to 50% of battery capacity) to charge batteries as quick as possible, even on cloudy days. Focus on catching the morning sun, when the batteries are at their lowest state of charge.
-
Keep the power on. During the hot rainy season - with the air-cons running hard and not much solar input - the backup generator will start automatically to supplement the solar. But even if the generator runs out of fuel the system will not shut down completely, but will shed heavy loads to keep the lights and fans on.
-
Batteries are the most expensive component and we have to look after them. We need to charge them to 100% once per week to meet warranty requirements and make them last as long as possible. For this reason, we always integrate with a backup diesel generator. We aim to rarely use it, but having this backup power supply available means we can confidently size our battery storage for the average daily usage, rather than for the worst case. This saves resources in the long run.
