Right first time

“The strings don’t add up.”

The same mistake costs different amounts depending on when you find it. At the desk it costs two minutes. On the roof it costs a crew, a van and a day, with the scaffold up and the customer watching from the kitchen window. At commissioning it costs all of that plus an explanation.

Installa checks the electrical side of the design while it is still a drawing: the strings against the inverter, and the battery and charger against the supply. You get the argument before the customer gets the quote.

While it is a drawing

The electrical side worked out before anyone is on the roof.

Strings and inverter

Voltage and current at both ends of the temperature range, and the MPPT fit.

Plain language

An error you must fix does not look the same as a warning you may live with.

Right first time

The string the inverter will not take

A string that is fine on a mild afternoon can sit over the inverter’s maximum voltage on a cold, bright morning, and drop out of the MPPT range on a hot roof in July. Installa works the strings out at both ends of the temperature range and tells you which one does not fit.

Everything it finds is written in plain language and sorted by how serious it is, so an error you must fix does not look the same as a warning you may decide to live with.

String sizing and how the arrays are shared across the MPPTs
Whether the components you have chosen work together at all
The battery’s coupling, voltage and charge and discharge rates against the inverter
Configuration warnings, grouped by severity

Not just panels on a roof

Most jobs now have more than one thing on the consumer unit. Installa validates each of these on its own, and validates them together when they go in as one system.

Solar PV

Domestic and commercial arrays, strung and checked against the inverter

Battery storage

Hybrid and added-later batteries, checked against the rest of the system

EV charging

Chargers taken into account with the rest of the load on the supply

Heat pumps

Sized and checked alongside whatever else is being fitted

Combined systems

Panels, battery, charger and heat pump validated as one installation

It warns. It does not sign off.

Better you know before you start than after.

Installa is a check, not an approval.
It will not stop you quoting a design it has complained about, because sometimes you know something it does not.
The judgement stays with your designer and your electrician, and so does the sign-off.
Installa does not produce certificates and does not submit anything to a grid operator or a certification body on your behalf.

Either side of the check

The validation reads the design and feeds the quote. Neither is a separate piece of work.

Planned exactly

3D solar design

Lay the panels out on the customer’s real roof, in the browser, before anyone is on a ladder.

Costed correctly

Quotes

The checked design becomes the priced quote, down to the cable runs, at your prices.

Everyone up to date

Scheduling

Book the crew once you know what the job really is, and tell the customer the date.

See it with one of your own jobs

Put in one real enquiry, draw the roof, check the design and send yourself the quote. You will know within the hour whether Installa would have caught the things that went wrong last month.
