What our customers say about us

Daniel

Excellent service

The entire process went smoothly. The website is simple and effective. The payment process was transparent and seamless. The shipment was on time, although the carrier split it into two packages with only one tracking number, which caused some confusion for me, but this was quickly clarified by Robinsun's customer service.

Benz Kotzen

Delivering to us in Portugal is difficult and despite the difficulties with the Portuguese postal system, the staff at Robinsun were extremely helpful. The plug and play system we ordered was delivered within the set time frame, all pieces present and well packaged and now we are getting the 800 kWh at peak sun as promised.

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.

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.

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.

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

Product FAQs

Storage

How does a storage system for my plugin solar kit work?

How does a storage system for my plugin solar kit work?

In short: as easy as a plugin solar kit.

There are different types of storage systems, can be divided into these main categories:

  • Storage for already installed plugin solar kits. If you already have a plugin solar kit with solar panels and a micro inverter installed, you can add a storage system between your solar panels and the micro inverter. These systems are generally very easy to install, and in some cases (like the Saturn C B2500) even expandable in a modular way.
  • All-in-one storage systems. If you want to add storage to your first plugin solar kit, an all-in-one solution is best. These systems combine batteries, controllers and micro inverters into a single system. You plug the solar panels in on one side, and connect the system straight to your home socket on the other.
  • Standalone storage systems. Recently a third category of storage systems has launched, that doesn’t need a direct connection to your solar panels or plugin solar kit. These independent storage systems connect to any household plug, and store all surplus power your solar kit produces. They charge and discharge through your home’s electricity network, and can also be charged with grid energy if you want to top up in low-cost times or have no solar installed at all.

Can I also charge my storage with power from the grid?

Can I also charge my storage with power from the grid?

In short: with a hybrid storage system, yes.

Most storage systems that have launched in recent months include “hybrid” charging. This means that the storage system can not only discharge into the home’s power network, but also charge from it. This functionality allows you to top up your battery with power from the grid. This makes sense if your power tariff has very cheap prices in some dayparts, when topping up costs little, and use that power in the more expensive dayparts.

How much storage do I need for my home?

How much storage do I need for my home?

In short: this depends on your consumption levels.

Storage needs can be looked at from several sides:

  • Solar kit production. If you look at how much your solar kit produces during an entire day, and how much you consume on the spot, the rest is what you will have to store. For example, if your Plus 2000 kit produces 8 kWh per day but during the day you only use 3 kWh, then you need at least 5 kWh of storage for your surplus, to use it when the sun doesn’t shine.
  • Household demand. If you know how much you consume per day at home after subtracting the immediate consumption of your solar kit’s production, you know what you're missing. A part of that can be covered by storing your solar kit’s surplus. The rest can be covered by charging in low-cost hours from the grid. For example, if you consume 10 kWh per day in the above example, you will need 2 kWh to charge from the grid on top of the 5 kWh mentioned above.

And remember, that when it comes to batteries, you should never discharge below 10% and never charge over 90%. This means that you can only use 80% of any battery capacity. This would mean that in the above scenario of 7 kWh of required storage, you will need a storage system of 9 kWh, whose 80%-capacity of 7,2 kWh covers your needs.

Will a storage system also work during power outages?

Will a storage system also work during power outages?

In short: Some of them do.

Several storage systems that have launched recently have an “AC outlet”, also known as “emergency outlet” or “anti-blackout”. This is a Schuko socket that delivers electricity when the network goes down. These systems can also be used in homes that are not grid connected.

During power outages, like the “apagón” in Spain, Portugal and parts of France in April 2025, these systems provide critical base power to their customers, literally “keeping the lights on”. With sufficient storage capacity, and daily recharge with your solar kit, you can easily get through power outages also for longer periods of time.
