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 in 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 1.5 kW of continuous power and 2.2 kW of peak power for 7 seconds.
How durable are WATTS?
We are confident in the high quality of our products, so we offer you a warranty for 2 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! WATTS Battery offers maintenance of your device by replacing the battery pack at 2000 cycles of full discharges. The lifecycle of a battery is the number of charge/discharge cycles it can perform until its nominal capacity is reduced to 70-80%. Modern lead-acid batteries are designed for 200-300 cycles, standard lithium for 500-800 cycles.
