1. Germany
FAQ: EM Series Hybrid Inverter for the German Market
Q1: Is the EM Series inverter certified for use with the German
Einspeisevergütung (feed-in tariff) system?
A: While our EM Series inverters are built to high international
standards and can be configured for grid-tie functionality, for
official feed-in to the public grid and receiving the
Einspeisevergütung, a VDE-AR-N 4105 certified inverter is typically
required. We recommend the EM Series primarily for optimal off-grid
and backup power solutions, maximizing your self-consumption of
solar energy.
Q2: With Germany's often cloudy weather, how efficient is the MPPT
at low light conditions?
A: Our advanced MPPT technology maintains high tracking efficiency
even in low-irradiance conditions, typical of German weather. It
starts at a low voltage and operates efficiently across a wide
voltage range (60V-500V), ensuring you harvest the maximum possible
energy from your PV panels throughout the day.
Q3: Can I use a German-brand lithium battery like BYD or Sonnen
with this inverter?
A: Absolutely. The built-in RS485 communication port supports
compatibility protocols with major lithium battery brands,
including leading German manufacturers. This ensures seamless
communication for optimal battery charging, discharging, and
lifecycle management.
Q4: What is the surge power capability for starting high-power
appliances like washing machines?
A: The EM Series offers high surge power (e.g., 7000VA for the
3.5KW model), which is more than sufficient to start inductive
loads from common German household appliances, ensuring they run
smoothly without interruption.
Q5: Is the pure sine wave output suitable for sensitive electronics
like German engineering tools?
A: Yes. The inverter produces a pure sine wave output, which is
identical to or even better than the grid power. It is perfectly
safe for all sensitive electronics, including high-precision
engineering equipment, medical devices, and computers.
Q6: How does the "No Battery Mode" function benefit me in Germany?
A: This feature allows the inverter to directly convert solar
energy into AC power for your home appliances during the day
without using the battery. This reduces battery cycling, extends
its lifespan, and provides immediate savings on your electricity
bill.
2. Australia
FAQ: EM Series Hybrid Inverter for the Australian Market
Q1: Is this inverter approved by the Clean Energy Council (CEC) for
use in Australia?
A: The EM Series is designed to meet rigorous international safety
and performance standards. For specific CEC approval required for
STC rebates, please check our latest certification list or contact
our local Australian distributor, as we are continuously updating
our certifications for key markets.
Q2: Can it handle the extreme heat in the Australian Outback?
A: Yes. The inverter is rated for operation up to 50°C (122°F). Its
robust design and detachable dust cover make it well-suited for
harsh, dusty, and hot environments, ensuring reliable performance
on remote properties.
Q3: The specs mention "No Parallel Capability." Can I still expand
my system later?
A: While individual EM units cannot be paralleled, you can design a
scalable system by using multiple inverters for different load
groups (e.g., one for the shed, one for the house) or by upgrading
to a single, larger capacity unit from our series as your energy
needs grow.
Q4: How does the high 120A MPPT current benefit my system in sunny
Queensland?
A: In high-sunlight regions like Queensland, a high-current MPPT
(up to 120A) allows you to connect large arrays of solar panels,
capturing more of the abundant solar energy and converting it into
usable power much faster, significantly reducing battery charging
time.
Q5: Is it true that I can activate a completely flat lithium
battery using just solar panels?
A: Yes! Our unique Lithium Battery Activation function via PV is a
game-changer. If your battery ever discharges to a zero-volt
protection state, you can use solar power alone to reactivate it,
eliminating the need for a costly service call, which is a huge
advantage in remote locations.
Q6: What is the warranty and service support like in regional
Australia?
A: We offer a standard warranty and are building a network of
certified technicians and service partners across Australia. We
ensure that even customers in regional areas have access to
reliable support and spare parts.
3. United States
FAQ: EM Series Hybrid Inverter for the US Market
Q1: Is the output voltage compatible with the US 120V/240V
split-phase system?
A: The standard model provides a 220V/230V output, which is
suitable for 240V split-phase applications. For full 120V/240V
split-phase capability, a separate external autotransformer may be
required. Please consult with our technical team for specific
wiring solutions for your home.
Q2: Does it have UL or ETL certification for safety?
A: Our inverters are CE and RoHS certified, adhering to strict
international safety standards. We are actively pursuing UL
certification for the North American market. Please inquire about
the certification status of specific models at the time of
purchase.
Q3: Can I use this as a backup power source for my home during a
grid outage?
A: Yes, this is a key feature. In SBU (Solar-Battery-Utility) mode,
the inverter will power your home from solar and battery. During a
grid outage (blackout), it automatically and seamlessly (within
10-20ms) switches to battery power, keeping your essential loads
running.
Q4: What is the "EQ function" mentioned for the battery?
A: EQ, or Equalization, is a controlled overcharge function that
helps balance the voltage of individual cells in lead-acid
batteries, preventing stratification and sulfation. This optimizes
performance and extends the battery's life. For lithium batteries,
the BMS communication handles cell balancing automatically.
Q5: How can I monitor my system's performance?
A: With the optional WiFi module, you can remotely monitor your
system's performance in real-time from your smartphone. Track
energy production, consumption, battery status, and diagnose issues
from anywhere.
Q6: Is the 500V DC PV input high enough for modern high-efficiency
panels?
A: Absolutely. A 500V Max PV Open Circuit Voltage allows you to
connect long strings of modern high-voltage panels, making system
design more efficient and cost-effective, especially for larger
residential installations.
