The balcony energy storage system includes solar panels, SolarFlow and micro-inverters. You can shop for PVHub and Hoymiles micro-inverters on the order 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 AB1000 with 960Wh of storage and AB2000 with 1,920Wh. Up to four batteries can be stacked in any combination, for a maximum total capacity of 7,680Wh.

The Hub 2000 has two MPPTs, 900W each and 1,800W in total. In order to utilize your solar system more efficiently, we recommend connecting each MPPT in parallel to solar panels with a total power of 1,000W, to maximize yield even when the sunlight isn't as strong. Please remember, for your safety, that the voltage of the PV panels accessed by each MPPT should be between 16V and 60V, and the current should not exceed 32A.

Each of Hub 2000's MPPTs is compatible with solar panels delivering a voltage between 16V and 60V and less than 32A of current. For each MPPT input, if connecting more than one solar panel, the panels must be wired in parallel.

At 1,920Wh, AB2000 has twice the capacity of AB1000 and is smaller in size than two AB1000's stacked together. AB2000 also has an automatic self-heating function that allows it to work in ambient temperatures as low as -20°C.

Yes, your solar system can include a total of four AB1000 and/or AB2000 batteries stacked together. However, AB1000 can only operate in ambient temperatures of 0°C and above whereas AB2000 works as low as -20°C. In addition, you can only stack 4 Batteries at most.

Step 1: You'll need to check your local regulations to find out how much power the balcony power station can provide to your household's circuts. Nowadays it's typically around 600W or 800W.

Step 2: We recommend choosing panels that can deliver a total of 2,000W, with 1,000W going to each MPPT.

Step 3: When choosing a battery configuration, it's ideal if the amount of energy you can store is equal to the amount of energy produced in one day.

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 AB1000 or AB2000 batteries.

If the PV power is greater than the micro inverter power set in the Zendure app, the batteries are charged. Otherwise, stored energy is discharged to cover the deficit. If your balcony power plant is equipped with both AB1000 and AB2000, the AB2000 switches on the self-heating function in cold weather from 0°C to -20°C, while the AB1000 only starts to work when the temperature rises to 0°C again.

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 PVHub and each storage unit are shipped in separate boxes, which may or may not be delivered at the same time. If more than seven days have passed since receiving a package, and you're still waiting for the rest of your order to arrive, please contact us..
