Product Description

--Rechargeable deep cycle lithium ion battery module inside for warranty 10 years use

--Flexibly can be OEM or Customized logo for overseas clients

--User-friendly operation main LCD screen display for clients to check and monitor easily!

Slim light weight and flywheel designed !

--Safety packaging for air and sea shipping


--Use solar energy throughout the day and at night
GSL ESS lets you enjoy the benefits of solar energy production 24-hours a day! Our integrated smart electronics manage energy use throughout the day, detecting when there's excess power and storing it for use at night.
--Never Worry About the Lights Going Out
GSL ESS is specifically designed to provide you and your family peace of mind in the event of a power outage. Our unique power detection system will sense outages in real-time and automatically switch over to battery power!
--Harvest Cheaper Energy to Use Later
GSL ESS allows you to engage in “rate arbitrage” – storing energy when it is cheap and running your home off the battery when rates go up. The GSL ESS is the right choice for every home and every budget.

How the sonnenBatterie gets you through the day
--Clean energy during the daytime, in the evening and at night.

Morning: minimal energy production, high energy needs.
At sunrise the solar panels start to produce energy, though not enough to cover the morning energy needs. The GSL battery will bridge the gap with the stored energy from the previous day.

Midday: highest energy production, low energy needs.
In the daytime the energy generated from the solar panels is at its peak. But since nobody is home the energy consumption is very low so that most of the generated energy is stored in the GSL battery.

Evening: low energy production, high energy needs.
The highest daily energy consumption is in the evening when the solar panels produce little or no energy. The GSL battery will cover the energy need with the energy produced in the daytime.

Why an energy storage system is necessary for you?

1. What is all-in-1 solar ESS?
GSL ENERGY ESS is the integrated solar power system with solar charge controller, AC-DC charger, lithium ion battery with advanced BMS, pure sine wave inverter with UPS function and other control circuits.

2. How does all-in-1 solar ESS work?
GSL ENERGY ESS powers your home by the energy generated from solar panels or stored battery power from solar panels while there is abundant sunshine or utility grid while the electricity price is low, or it can also power your home by utility grid power directly in case battery power used out and sunshine is not available.

3. What can all-in-1 solar ESS do?
GSL ESS lowers your electricity bill and you can sell the exceeded solar energy to grid for profit. It offers independence from the utility grid and the security of an emergency backup. Using the APP of smartphone, monitor your solar production anywhere, anytime. GSL makes you enjoy solar green energy and uninterrupted power supply.

Energy Storage is the development tendency.

The earlier encouragement policies stimulate the development of solar energy grid tied system and rooftop PV installation. But recently, more and more countries started lower FiT or even cancel FiT. ESS becomes installer’s demand. GSL ENERGY all-in-1 ESS comes up for this background.
