Complete Photovoltaic Kits | Off Grid, Plug & Play | MR WATT

photovoltaic kits

MR WATT photovoltaic kits are complete solutions that include solar panels, inverters and—where applicable—storage systems already matched and tested together. Whether you are looking for an off-grid photovoltaic kit for a home not connected to the grid, a plug and play system for the balcony, or a standalone system for a cabin, camper or swimming pool, here you will find the kit already configured and ready for installation.

Which photovoltaic kit is right for you?

The choice mainly depends on how the system will be used and where the user is located. Here are the available categories:

  • Home photovoltaic kits (off grid) — standalone systems for homes not connected to the power grid. They include a hybrid or off-grid inverter, batteries and panels sized to cover basic household consumption.
  • Plug and play kits — quick solutions for balconies or terraces, compliant with CEI 0-21. Ideal for reducing your bill without complex authorizations. Power from 400 W to 1 kW with integrated micro inverter.
  • Cabin and countryside kits — off-grid systems for shelters and rural homes with limited access to the grid. Sized for essential loads: lights, refrigerator, small appliances.
  • Camper and marine kits — flexible or rigid panels for installation on the roof of campers, caravans and boats. Compatible with 12/24 V MPPT controllers.
  • Swimming pool kits — photovoltaic systems dedicated to powering pool pumps and filters, with storage to ensure continuity even in the evening hours.

What does an MR WATT photovoltaic kit include?

Each kit is made up of selected components that are compatible with each other. Depending on the type, you will find:

  • Monocrystalline or bifacial photovoltaic panels (power from 100 W to 500 W per module)
  • Off-grid, hybrid or micro inverter (depending on the application)
  • MPPT charge controller (in off-grid and camper kits)
  • AGM, GEL or LiFePO4 batteries (in kits with storage)
  • Pre-assembled MC4 cables and connectors

Frequently asked questions about photovoltaic kits

What is a photovoltaic kit and what makes it different from buying the components separately?

A photovoltaic kit is a set of components already selected and sized to work together: panels, inverter, charge controller and—in off-grid systems—batteries. Buying a kit avoids compatibility errors between components (e.g., incorrect string voltage compared to the inverter) and simplifies installation, since all elements are balanced for the same rated power.

What is the difference between an off-grid photovoltaic kit and a plug and play one?

An off-grid kit is a system completely independent from the public power grid: it produces energy, stores it in batteries and supplies it even at night or with cloudy skies. It is designed for isolated homes, cabins and systems not connected to the utility. A plug and play kit, on the other hand, connects to the home grid via a standard Schuko or CEI 17-13 socket, feeds directly into consumption and reduces the bill, but does not store energy: when the sun sets, the system shuts down.

Do balcony plug and play kits require authorizations?

Plug and play kits up to 800 W compliant with the CEI 0-21 standard can be installed without building permits and with simple communication to the grid operator (in many cases only a prior notification). For higher power levels or in the case of a condominium, it is necessary to check local provisions and condominium regulations. MR WATT provides kits already compliant with CEI 0-21 with a certified inverter and included documentation.

How much space do I need to install a 1 kW off-grid photovoltaic kit?

A 1 kW kit with 500 Wp panels requires about 3.5–4 m² of south-facing surface with an optimal tilt of 30–35°. With 400 Wp panels it comes to about 4.5–5 m². Average annual production in central-southern Italy is about 1,300–1,500 kWh/year per kWp installed, with peaks in summer and lower values in winter.

Does MR WATT offer assistance in choosing the photovoltaic kit?

Yes. MR WATT’s technical team is available via chat, phone and e-mail to support the choice of kit based on actual consumption, available surface area and the type of installation. MR WATT also produces custom photovoltaic panels—custom sizes and power—for special applications where standard formats are not suitable.
