One cable, double function

Charging and discharging happens through the same power cable. Just plug the battery into a regular socket, and it automatically switches between charging and powering your home.

What our customers say about us

Harry O'Connor

Amazing support and great prices. What's not to like? Really lovely people on WhatsApp helping you with everything. Don't delay, invest in solar!

Wies Verstraete

The service of Robinsun is outstanding

The service of Robinsun is outstanding. Although the panels were damaged in the transport (which wasn't their fault), they did everything to send new panels asap. Very easy communication via WhatsApp.

Paul Brabant

Get your equipment here

I only have good things to say about this company. I haven't experienced customer like this in Spain. Reminds me of the best companies in the US, where the customer is king. Super easy installation, quick software install, and up to 1.3kwh with 4 panels. Brilliant.

“Excellent Solar Investment and Outstanding Service“

Purchasing the solar system has been a great decision. We’ve reduced our electricity bills by over 50% with just four solar panels. The service was very fast, and the advice was equally excellent—they helped us throughout the entire documentation process. We’ll continue buying their products because we find them to be high quality, and their customer service is outstanding

5 Star After Sales Service
I would like to thank Boris and his team for swapping out the TSUN storage battery for the ANKER Solarbank through no fault of Robinsun's the manufacturers TSUN admitted there was a problem with their equipment. The Anker is working great and giving us power all through the evening and is usually fully charged at this time of the year just after lunch. Robinsun's after sales service is second to none. 5 stars plus.

Luis Gomes

Excelent products and excelent support.

Excellent products and excellent customer support. I bought a solar kit, and from the very first moment, the support via WhatsApp was excellent. Very fast delivery to Portugal without any problems. Everything worked perfectly, and I was very satisfied. I recommend Robinsun and will buy from this company again in the future.
