A young family with three kids moved out of city immediately after the pandemic started in the spring of 2020. Their house was still in construction, and they were still in the process of buying additional household appliances; only a pump, a septic tank, and a boiler were installed in the house. The owners were visiting the site quite often to check on the construction state. But as soon as March 2020 arrived, all of their plans had to change. The whole family immediately moved into the dacha.

While the first days seemed to be just fine, during the second…


1. Why does UPS for homes need online monitoring?

We are used to thinking that the power supply system (UPS) is some kind of device on the floor that works independently and has only one button to turn on. However, modern uninterruptible power supplies for the home are full-fledged power plants (especially if you install solar panels). Such systems not only accumulate electricity from the external network to supply the load during the power outage, but also generate electricity.

Products of this class have an internal monitoring and control system that ensures an uninterrupted power supply to the load. However, the management and monitoring system will work most effectively…


Batteries are all around us. We use them in smartphones, home appliances, cars, and, of course, for backup power systems. Each application uses a different type of battery. Depending on the electrode material and the type of electrolyte, there are different variations of battery cells, each of which has its own characteristics.

What kind of batteries exist?

1. Lead and gel batteries

Despite the age of the technology, lead-acid batteries are still used in backup power systems, road transport, and renewable energy storage systems.

Certain types of lead-acid batteries are used in uninterrupted power supplies (UPS). Such batteries are the Absorbent Glass Mat (AGM) type, in which a special porous…


To be successful in a technological startup, first you need to think about developing the RnD (Research and Development) department. It is the heart and the brain of the company, where ideas are born and — implementing to real life.

  1. How RnD is developed in Watts Battery

70% of our employees are part of RnD department. There are research engineers, designers, architects, technologists workers, power electronics developers, control systems and cloud services programmers, etc. …


Our company launched the cloud-based platform LINK allowing end-users participate in the energy market and make money.

Watts Battery.LINK is a platform that collects and aggregates behind-the-meter data from every cloud-connected and registered WattsBattery module. Such information is vital for utilities experiencing continuous changes and technical challenges in their networks due to the rapid adoption of renewable energy technologies by residential customers. Watts Battery.LINK offers visibility to the grid edge while providing valuable power quality information to help utilities plan their networks more effectively. …


The cost reduction in Solar PV and the incentives rolled out in several countries and across the world are the two main factors for the rapid adoption of this technology by the householders. The incentives that are mostly based on feed-in-tariffs and net-metering schemes provided opportunities to householders to save on their electricity bills through the generation of solar energy.

However, these incentives, and as every incentive aiming to promote and accelerate the adoption of new technologies, are gradually phasing down (1-5). This means that all surplus energy generated by your solar system will be exported back to the grid…


Five years ago, we were thinking about creating a product that will change the energy market and people’s lives. At that time, the interest in solar energy products had already gained momentum internationally and the need to store and use clean energy was becoming evident. While several energy storage products started appearing in the market they required (and still do) hours to days of costly and complex professional installation making the access to renewable energy a privileged feature accessible to only a small part of the population. Then comes our idea to make a product that would substantially simplify the…


Recent years have seen an increased number of household owners (around the world) in adopting residential energy storage systems. This trend — which is in a largely driven by (1) the gradually falling prices of the residential energy storage systems, (2) the increase in residential electricity prices, and (3) the reduction of solar PV generation feed-in-tariffs — enables household owners to store the excess of their solar PV generation during the day and use it later at night, hence reducing their carbon emissions and electricity bills even further.

Looking at Figure 1, the gradually battery pack costs reduction has contributed…


WATTS Battery is a portable energy system that generates a constant supply of energy while driving costs down.

WATTS Battery offers one of the lightest and most powerful residential battery energy storage systems for both off-grid and on-grid applications. Our product provides an all-in-one, user-friendly, multi-source power system that allows households to use, manage, and transfer solar and grid electric power, reducing peak tariff consumption.

The compact, all-in-one, modular and plug-and-play design of WATTS Battery offers a unique opportunity to scale up by merely adding additional WATTS Battery modules on top of each other until the desired power and energy…


It’s hard to imagine our modern world without electric mains. People settle at those lands where these mains are installed, or they have to sacrifice their own comfort. We are used to have electricity at home all the time, that is giving us lights, making household appliances, water supply and heating work. But technologies are developing, engineering solutions are becoming more complex and modern. As a result, high tech products are born, which allow to solve electricity problems and even to choose the place where you really want to live.

Watts Battery is a full-featured energy management system, it’s a…
