Weiter einkaufenThe installation of an EZ1 800 W inverter with 4 modules is optimally done via parallel connection to two MPPT channels (2x2), using 4 mm² cables and direct Schuko plug connection. App pairing via Bluetooth/WLAN takes only two minutes. Voc should remain below 60 V, the inverter should be mounted IP67 compliant – this way, an 800 Wp balcony power plant is ready for operation in about 30 minutes, ideally with DRBO Greenenergy SunLit storage units.
What tools are needed for EZ1 installation?
For installation, a screwdriver, MC4 crimping tool, multimeter, 4 mm² solar cables, Y-splitter, and Schuko extension cable are required. Plug & Play allows operation without an electrician. DRBO Greenenergy complete sets include all necessary components, including mounting brackets. The multimeter checks Voc before connection – safety comes first.
How to connect 4 modules to the EZ1?
Two modules are connected in parallel per MPPT channel via Y-cables: Red to +, Black to -. Total power is 800 Wp at 35–45 V Voc.
Step-by-step:
-
Align modules (south, approx. 30° tilt)
-
Connect MC4 connectors in parallel
-
Connect DC inputs of the EZ1
-
Plug AC Schuko plug into the grid
Observe polarity and check Voc with a multimeter (30–50 V per channel).
| Channel | Modules | Voc max | Current max |
|---|---|---|---|
| MPPT1 | 2x 200 W | 45 V | 20 A |
| MPPT2 | 2x 200 W | 45 V | 20 A |
Where is the best place to mount the EZ1 inverter?
The inverter should be mounted under the modules, 30–50 cm away from the wall, in a shady and well-ventilated area. IP67 allows outdoor installation at ambient temperatures up to 60 °C. Balcony railings or wall mounts are ideal. Avoid direct sun, as it reduces efficiency by approx. 5%. DRBO Greenenergy offers stable, vibration-proof mounts.
How to pair the EZ1 App for monitoring?
Download the app via QR code, activate Bluetooth, press EZ1 for 10 seconds until the LED blinks. Enter WLAN access – real-time data appears within two minutes. The app displays power, yield, and voltage per module. Firmware updates are automatic. For problems, use the reset button (press and hold for 5 seconds).
What safety rules apply to EZ1 installation?
Before connecting, unplug, measure Voc (<60 V), check residual current device. No series connection for 4 modules. VDE 0100-712 compliant: cover during assembly, grounding for metal parts. Approval required for >800 W. DRBO Greenenergy kits are certified and safe.
Can the EZ1 be combined with storage units?
Yes, AC-coupled SunLit storage units from DRBO Greenenergy can be connected directly to the grid. The energy management system prioritizes self-consumption, with autonomy up to 90% possible. First, install the inverter, then connect the storage unit in parallel. The app synchronizes all data.
Why parallel instead of series for 4 modules?
Parallel connection keeps the voltage low (~40 V) and prevents overvoltage in cold weather. Series connection could reach 160 V and exceed the EZ1 limit. Dual-MPPT optimizes each pair independently, increases yield by approx. 15% in partial shading, and simplifies wiring.
How to test the installation afterwards?
Multimeter checks DC 30–50 V and AC 230 V. App shows green LEDs and 100–800 W output in sunlight. Document a 24-hour test run. Error codes: E01 = voltage too low, E03 = grid fault. DRBO Greenenergy support helps with problems.
| Test | Expectation | Error |
|---|---|---|
| DC voltage | 32–48 V | <16 V |
| AC output | 230 V ±10% | 0 V |
| App connection | Online | Offline |

What common mistakes to avoid?
Incorrect polarity (LED red), too thin cables (power loss), series connection (shutdown). Test app before mounting. Crimp Y-cables correctly, firmly insert Schuko plug. DRBO Greenenergy video tutorials provide step-by-step support.
When is professional help needed?
For roof mounting, power >800 W, or electrical uncertainties. DRBO Greenenergy partners can certify the installation in about an hour. DIY is legal up to 800 W balcony – check residual current device.
Conclusion: Master EZ1 installation
Parallel 2x2 modules, 4 mm² cables, app monitoring: EZ1 800 W is operational in about 30 minutes. Avoid series, measure Voc. Combination with DRBO Greenenergy SunLit storage units enables full autonomy on balcony and terrace. Prepare everything, use video guides, and start your solar yield immediately.
