Advantages of Containerised Solar Solutions

Off-Grid Capabilities

Containerized solar solutions with battery storage provide off-grid capabilities, allowing factories to operate independently from the grid even during grid outages or load shedding events, enhancing operational resilience and reducing production downtime.

Hybridisation Potential

Containerized solar solutions can be integrated with other energy sources, such as generators or wind turbines, to create hybrid power systems, allowing factories to optimize energy production and storage based on the availability of different resources, improving energy reliability and cost-effectiveness.

Containerized, pre-built, solar solutions are designed for quick and efficient deployment, benefiting from solar energy immediately. The pre-built system can be transported to the factory site and installed relatively easily, minimizing installation time and disruptions to factory operations.

Energy Management and Control

Containerized solutions use advanced energy management and control systems to monitor and optimize energy generation, consumption, and storage, enabling better decision-making, energy efficiency improvements, and cost optimization.

Mobility, Scalability and Space Optimisation

Offer mobility and scalability, easily transported and deployed to different locations, or expanding operations with minimal infrastructure changes.
This is beneficial for factories with multiple sites or planning future expansions

Maintenance / Monitoring Ease

Containerized solar solutions include integrated monitoring and maintenance systems, that provide remote monitoring, fault detection, and preventive maintenance, reducing downtime, improving system performance. Containerised solutions simplify maintenance activities.

Installing Equipment on Site
The most common solution is to install the equipment on site in a dedicated room. The room where the inverter/s are housed will need to be cooled as the solar inverters produce heat.

We calculate the size of air conditioning units for the different solutions. Normally the batteries require far less cooling than the inverters.
Some site call for added power or for redundance and then a parallel solution is available.
Example of an almost completed Parallel System with 2 x 150kW Atess Solar Inverters operating in parallel coupled to 2 x 200kW Freedom Won LiFePO4 Batteries also in parallel as.shown below

Solar and BackUp Intelligent Load Control

Placeholder Picture

What is Intelligent Load Control and why is it needed?

There are many reasons why it's needed.
Probably one of the most important reasons for implementing it is the cost saving benifits.
The highest cost component in a quality BackUp system is the Lithium Iron Phosphate (LiFePO4) Battery and the larger this battery the longer autonomy (Back Up Time), however the larger the battery the higher the initial outlay cost.
As a compromise using a Parallel Systems Industrial designed load control system you could prioritise your electrical loads and by having the load control system intelligently "shedding" the non critical loads e.g. water heaters, etc, when cetain conditions are present i.e. Utility Failure, low battery state of Charge or even low sun power potential if you have solar connected, your autonomy would be greatly extended. i.e. you could get by with a smaller battery
Features of the Parallel Systems (Pty) Ltd  Load Control System

Allows user to monitor the following on any browser connected to the network:-
 Instataneous Battery State of Charge i.e. Battery %
 Instantaneous Potential Sun Energy i.e. How much power you can extract from the current sunlight.
Amount of Power being consumed from Generator or Utility
Amount of Power being consumed from Solar Inverter/s
Total Amount of Power being consumed by your connected Load

Load Control
Any Loads wired via contactors and connected to the Load control system will be automatically shed by user preset values. You are able to select all or individually select which one you require for each load set. e.g. Sun Potential, Battery State of Charge, Solar inverter Output Power Level. You can set at which level the load should be disconnected and also at which level it should be re-connected.

Alternate Supply Control  i.e. Generator or Utility
There is a separate setting page for controlling your generator or Utility Supply Contactor. 
You are able to set at which Battery Level (State of Charge) and /or at which Sun Power Level your Alternate Power Supply should be energised. There is a value level for 24/7 operation and a separate setting to check your preset battery level value every day at Sunset and to energise your Alternate Supply to "Top Up" your battery level to that preset value so you are garanteed of having a "Topped Up" battery every day to get your critical load through the night. This is especially important after cloudy days. The System will be able to calculate your Sunset times after you have entered your Longitude and Latitude for you site location.
