Limited space? The new Performance 400 plugin solar kit is the solution for your energy autonomy

Many families have told us that they don’t have enough space to install two or more solar panels at home. Their houses lack a private roof or garden, and some balconies are rather small. That’s why we’re launching the new Performance 400 solar kit, ensuring that everyone has the opportunity to save on their power bills.

In this blog, we’ll show you the highlights of the new Performance 400 and how you can start saving quick and easy with Robinsun’s smallest plugin solar kit.

Make the most out of your limited space!

While our solar kits Plus with their four panels are ideal for bigger spaces, the new Performance 400 solar kit with one panel can be installed on a balcony, terrace, roof, or wall. 

You just need a minimum space of:

• 172x113 cm (size of our QN Solar Silver Frame and QN Solar Full Black panels).
• 175x113 cm (size of our premium Aiko Neostar2 panel).

With just this small space, you can install a solar kit, as the mounting brackets adjust to the panel size and don’t require any additional space. 

The microinverter, measuring less than 20 cm and weighing under 2 kg, can be mounted behind the panel using the included accessories set.

So if you are motivated to start saving on your power bill, you can do so with minimal installation space.

A smarter brain for more production: the new Tsun MS-400-Balcony micro inverter

The Performance 400 comes with a new upgrade: the latest-generation 2025 Tsun MS-400-Balcony microinverter, which is optimized for one-panel solar kits that fit into homes with limited space.

The MS-400-Balcony microinverter features the latest improvements:

• Upgraded Wi-Fi card: The improved Wi-Fi card offers a stronger WiFi signal, resulting in a longer range. This allows greater distance between your installation and your home router, giving you better control of your energy production through the app.
• No loose cables: The optimized design ensures that there are no loose cables for daisy-chain connections or additional panels. This keeps all connections sealed, enhancing protection against weather conditions and ensuring greater safety for your kit.
• New cable: The new Exceedconn cable features a threaded lock. This, as well as the pressure connector, ensures that all your connections are well protected and totally watertight.
• New insulated exterior: The new protective coating offers greater heat resistance to prevent overheating.
• Schuko plug output: The best features remain! The new devices are just as easy to use as before, featuring a Schuko plug output that can be connected directly to your nearest outlet, allowing you to start saving from day one.
