FAQ

What is a solar kit?

A set of products chosen to work together: panels, an inverter or charge controller, batteries if needed, and mounting hardware. At ASE Energy, a French distributor, these kits sold without installation are mostly for handy homeowners, but also for mobile projects (vans, boats, motorhomes) and for some professionals who always buy the same configuration. A good kit comes with a wiring diagram showing the right cable sizes and where the protection devices go.

How do you choose the right solar kit?

Start by listing what you want to power and for how long, to establish a daily need in kilowatt-hours. That need determines the battery bank, then the panels, the charge controller and the inverter. The site matters too: roof or ground, orientation, available area and room for the batteries and inverter.

What is the most common mistake?

Undersizing. A system that is too small wears out the batteries early and they will need frequent replacement: in the end, it costs more than a slightly bigger system from the start. ASE Energy adds about 20% margin to the stated needs, because people often forget one or two appliances. The balance between panels and batteries must also be respected.

Is there a connection order to follow?

Yes: each device has its own instructions. On an MPPT charge controller, for example, always connect the batteries before the panels. Read at least the key steps in the manual and, if in doubt, ask a technician for help.

Can you install a grid-tied kit yourself in France?

Yes, but with paperwork: a declaration to the town hall, a self-consumption agreement with Enedis and, according to ASE Energy, a Consuel certificate above 3 kWp. Selling surplus energy requires an RGE-certified installer.
