A balcony energy storage system consists of solar panels, a solar energy module, batteries, and a microinverter

The necessary components, including Hoymiles microinverter, are available on our SolarFlow Balcony Power Plant product page.

Solar panels often produce more power than a home needs at various points throughout the day. The excess energy is fed to the grid with no benefit to the person who generated it. SolarFlow lets you make the most of your solar panels by routing the extra energy to at-home storage so you can use it later and reduce your energy costs.

SolarFlow's compatible energy storage modules include AB2000 with 1,920Wh of storage.

Up to four batteries can be stacked in any combination, for a maximum total capacity of 7,680Wh.

Our Hub 1200 has two 500W MPPTs for 1000W total input. In order to utilize your solar system more efficiently, we recommend connecting each MPPT in parallel to solar panels with a total power of 650W, to maximize yield even when the sunlight isn't as strong.

Please note that the voltage to each MPPT must be between 16V and 60V, and the current should be less than 20A each.

Each of Hub 1200's MPPTs is compatible with solar panels delivering a voltage between 16V and 60V and less than 20A of current.

In addition to the self-heating function the AB2000 already had, the AB2000S battery now features an aerosol fire suppression system for additional safety and protection.

Like their predecessors, both the AB2000 and AB2000S have the same robust casing and battery management system with protection against overheating, overcurrent, overvoltage, and short circuits.

Yes, all four batteries are compatible with one another and can be stacked in any configuration of up to 4 batteries total.

First, check with your local regulations to determine how much power a balcony system can supply to the household. It's usually around 600W-800W, in which case we recommend selecting solar panels that deliver 1,1000W-1,300W, respectively.

For storage, it is usually ideal if the capacity is enough to cover your evening energy consumption.

The Zendure App lets you set the amount of power going to your home via the micro-inverter, and excess power will be distributed to storage in the AB2000 or AB2000S batteries.

If you're generating more solar power than the micro-inverter power you've set in the Zendure App, the batteries will be charged with the excess power. If instead there is a deficit, the batteries will be discharged to suppply energy to your home.

Please note that our AB2000 or AB2000S batteries have an automatic self-heating feature that allows them to work in temperatures as low as -20°C.

Determining your daily energy consumption is an important step in configuring the right system for your needs. The goal is to generate more energy than you need during the day so that the surplus energy is stored and is sufficient to cover your evening consumption.

After sunset, check your energy meter and write down the reading. Then, after sunrise, take another reading and write this down. The difference between these two figures is the energy consumed. At the next sunset, read the meter again and subtract the sunrise figure to calculate the energy you used during the day.

Please keep in mind that energy usage and daylight availability fluctuate depending on the weather and the season. It may be helpful to project energy consumption for other seasons by checking the rated power consumption of your major appliances and anticipating how much more/less they will be used throughout the year. Power consumption information is often provided by the manufacturer but can also be determined using smart plugs with energy monitoring capability.

Yes, the Hub and each storage unit are shipped in separate boxes, which may or may not e delivered at the same time.
