HOW DOES SOLARFLOW HUB 2000 WORK?

DAYTIME
NIGHTTIME

During the day, power generated from solar panels flows through Hub 2000. Some of the power is converted into AC through a microinverter to run your home appliances. Excess power is routed to batteries so the stored energy can be used at night, Hub 2000 can handle up to 1,800 W of solar power, and the microinverter output can be set between 0 and 1,200 W. This level of power management helps you get the most out of your balcony solar system.

At night, the excess energy stored in the batteries (expandable up to 7680 Wh with 4 batteries) continues to power most of your home appliances: from high-wattage household appliances such as air conditioners, refrigerators to low-wattage appliances such as Wi-Fi routers， lights, laptops and more.

FAQS

What is the difference between Hub 2000 and Hub 1200?

The Hub 2000 can access higher power PV panels, supporting up to 2,400W. The payback cycle for the Hub 2000 is less than 3 years when used in combination with 2 AB2000's,and 2,000W of PV panels.

What are the model names, dimensions, and weights of each SolarFlow component?

Hub 2000 Model: ZDHUB2000, dimensions (W x D x H): 363 × 64 × 246 mm, weight ≈ 5.2 kg;

AB2000 Battery Model ZDAB2000, dimensions (W x D x H): 350 × 200 × 298mm, weight ≈ 21.62kg

Can I purchase SolarFlow without paying VAT in Germany?

Yes. According to the German Value Added Tax Act (UStG) § 12 tax rates, you can buy SolarFlow without VAT

For a better shopping experience, we recommend visiting our German website to enjoy tax-free prices on your orders.

What devices do I need for a balcony energy storage system?

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.

How can I benefit from using SolarFlow?

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.

What is SolarFlow's capacity?

SolarFlow's compatible energy storage modules include AB2000/AB2000S with 1,920Wh of storage. Up to four batteries can be stacked in any combination, for a maximum total capacity of 7,680Wh.

How many solar panels can be connected with SolarFlow?

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.

What kind of solar panel is suitable for SolarFlow?

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.

Compared to AB2000, what are the improvements in AB2000S?

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.

Can AB2000 and AB2000S be used in combination?

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

What safety certifications does SolarFlow have?

FCC, CA65, CE, RoSH, REACH, TÜV Mark and TÜV CE

I am new to solar products. How can I set up my balcony power plant system with storage?

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.

How is available power destributed between the home and storage (AB2000/AB2000S)?

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.

When is the battery charged and discharged?

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 AB2000 and AB2000S, the AB2000 and AB2000S switch on the self-heating function in cold weather from 0°C to -20°C.

How can I determine my daily energy consumption?

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.

Are the PVHub and batteries shipped separately?

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..
