The ABCs to ESS

• I am confused by the industry’s fancy words. What is ESS??

ESS stands for Energy Storage System, which is a combination of storage inverter (hybrid inverter) and battery.?

But random hybrid inverter and battery could not form an ESS, they must be compatible. Within each ESS is a control center (EMS - energy management system), a chip normally located inside the inverter. The chip will send signals to the inverter and the battery to let them know when to charge or discharge the battery. So the chip needs to speak a language that both inverter and battery understand - this is what we call compatibility.?

One battery tends to be compatible with multiple brands’ inverters, but we recommend ESS from the same manufacturer for 2 major reasons:?

1. Inverter and batteries are born as siblings, so they speak the same language from the very beginning.?
2. You know who is responsible if you need any help regarding to maintenance and after-sales issues instead of facing buck-passing from multiple manufacturers.?

• 7 Reasons to go solar with GoodWe ESS (Energy storage system)?

1. Minimize electricity costs by using free solar energy as much as possible.
2. Fight back load-shedding and blackouts once and for all.
3. Get access to all possible solar scenarios: produce, use, store and sell solar energy with an all-in-one solar system.
4. Energy independence and energy freedom.
5. Be free from the increasing electricity price and unstable power supply.
6. Get involved in grid auxiliary and become a prosumer in which applicable.
7. Dramatically reduce the cost of diesel generators and fossil oil while GoodWe batteries barely need maintenance.

• How does the solar system works in daily lives with a battery installed??

In most scenarios, solar panels will start working in the early morning, supporting the home load directly while the surplus energy is stored in the battery. The battery usually gets fully charged at noon or early afternoon, then the surplus energy will feed into the grid and gain some income for the homeowner.??

Solar panels will stop working from dawn as the sun goes down, at which the battery will kick in and become the primary power source for the load consumption. As time goes by, the battery runs out of its energy at midnight and starts charging from the grid enjoying the super off-peak electricity rate.?

• What are we talking about when we are talking seamless switch during the blackout??

When a blackout occurs, GoodWe ESS automatically starts discharging and powering the home appliance within 10ms. Homeowners will not even notice there is a grid outage event until there is a neighbor knocks on the door and ask “You got a generator or something?”
