Typical Connection Schematics

1. Connection to the distribution panel of a grid-connected house
This connection type will supply all loads connected on the corresponding phase. Solar panels are directly connected to the WATTS system and Solar energy is used to supply the load, and any surplus is stored in the WATTS system to be used later on the day.

2. Wall socket connection to backup individual appliances
This connection is similar to a UPS operation. WATTS module charges from the wall socket and appliances can directly be connected to the WATTS system sockets.

Frequently Asked Questions

Why should I use WATTS?

WATTS allows for the creation of a personal independent power plant from any available source of energy (solar panels, wind generators). It's as easy as turning on the TV, just plug it in the socket and press the power button.

We offer you the opportunity to be independent from energy companies, power line accidents, power supply failures, etc.

WATTS is an environmentally friendly energy source, just attach solar panels to it and say NO to harmful emissions from fuel power plants!

How much power does WATTS provide?

One module provides 1.5kW/2.2 kW at peak. Please check out this chart for more information

How durable are WATTS?

We are confident in the high quality of our products, so we offer you a guarantee for 7 years from the date of purchase of the product. 

What’s the deal with battery lifecycle?

Our engineers ensure that lithium-ion batteries installed in WATTS can withstand up to 2000 cycles! This will allow you to use one battery much longer than other manufacturers. WATTS Battery offer you the maintenance of your device in good condition by replacing the battery pack at 2000 cycles of full discharges.

More information:

The lifecycle o a battery is the number of charge/discharge cycles a battery can perform until its nominal capacity is reduced to a certain value. In modern batteries, this value is 70-80%. After the end of the life cycle, the battery does not stop working, but loses a certain percentage of its capacity. Modern lead-acid batteries are designed for 200-300 cycles, standard lithium - for 500-800 cycles.
