A person checks and specifies it
An ESM specialist checks the components and ancillary parts, then sends your itemised system specification and supply-only quote.
Complete equipment specification
We specify the complete package: suitable inverter and battery capacity, solar equipment where relevant, cables, CT and metering requirements, junction boxes, EPS equipment, compatible accessories and provision for future expansion.
A professional quotation you can act on
You receive a clear, itemised supply-only quotation and a documented recommendation to work from with your own electrician or installer. You can also ask questions about the proposed system before ordering.
Who this service is for
From a complete solar PV system to a battery retrofit, this is for anyone who wants a real person to check the full equipment list before committing.
Homeowners buying supply-only
Get a practical specification and a complete equipment quote you can review with your own electrician or installer.
Installers and electricians
Save time on equipment selection and ancillary parts for a full system, or ask us to review a less familiar product combination.
Self-managed projects
If you are sourcing a solar or battery kit yourself, get a second pair of eyes on sizing and compatibility. Your qualified installer makes the final site and electrical decisions.
