Daily energy use
We establish how much energy the site needs and how it is used. That informs battery capacity, generation and the periods the system needs to cover between charging opportunities.

Your site, your priorities
Reliable power starts with understanding the load.
A remote location, an expensive grid connection or a generator that runs for too many hours can all be reasons to consider off-grid power. The right starting point is a clear picture of what the site needs to run, when it runs and how that changes through the year.
SES assesses the practical options, designs the system and can take it through installation, commissioning and handover. We also provide independent design and technical support where you already have a delivery team.
The design decisions
Designed for the whole year.
A useful design accounts for everyday operation, demanding loads and the periods when renewable generation is limited.
Peak demand
Pumps, motors, cooking and other large loads affect inverter capacity and the way equipment can operate together. We assess starting demands as well as normal running power.
Winter operation
Seasonal solar output, shading and site use shape the design. Generator support and operating priorities are considered from the outset, with realistic expectations for the quieter solar months.
System integration
Solar, batteries and generators, working together.
The controls, charging arrangements and electrical distribution matter as much as the individual products. SES brings them together around an agreed operating plan, including generator control and remote monitoring where appropriate.
We work independently of any single manufacturer. Equipment is selected for compatibility, suitability and support, with provision for future expansion where the project requires it.
What SES delivers
From first assessment to a system you can operate.
Explore independent design and consultancyAssessment and design
Review the site and loads, compare supply options, establish the system architecture and define equipment, protection and installation requirements.
Installation and commissioning
Deliver the agreed installation, configure the controls and test operation across the available supply sources and intended loads.
Handover and ongoing support
Explain normal operation, monitoring, maintenance needs and system limits. Agree the scope of any ongoing technical support.

Before you decide.
Every site is different. These are useful starting points for a conversation about yours.
Can an off-grid system supply a home throughout the year?
Yes, with a design matched to the property and its energy requirements. The assessment needs to cover winter generation, peak loads and periods of poor weather. Generator support is often part of a practical year-round solution.
Will I still need a generator?
That depends on demand, renewable resources, battery capacity and the level of resilience required. We assess when a generator would be needed and how it would be controlled, rather than assuming solar and batteries will cover every condition.
Can you expand or investigate an existing system?
Yes. We can review an existing installation, investigate operating problems and assess expansion. Reusing equipment depends on its condition, compatibility and capacity, alongside the suitability of the existing wiring and protection.
What determines the cost?
The main factors are the loads, required running time, generation available, battery and inverter capacity, and the work needed on site. We establish a clear scope before pricing; a list of panels and batteries alone does not define a complete installation.
