Our microinverters are long-lasting, easy
to install with incredibly low failure rates.
What we provide | Micro-inverter

What we provide | Micro-inverter

NO.1 CEC weighted efficiency (96.5%) in the
world, modular MPPT ensure 10~30% more
yield of PV energy comparing string inverters
High efficiency
Well chosen components ensure its high quality:
MTBF (mean time between failure) > 550 years;
yearly failure rate < 0.18%; warranty of 12 years
High reliability
Real-time monitoring world widely to control
status of power generation for each module.
Online trouble shooting, quicker and precise
High accuracy
Only 40V at DC side in system of micro-inverter
would totally solve the PID effect, which will
highly improve energy yield and maintenance
Solution of PID
Upto 40V at DC side in system of micro-inverter
would avoid any possible risk of conflagrations
caused by strong drawing arc and electric shock
High security
Available for various installations of PV system
for modules in different orientation, shadings,
also power extension or reformation of system
High flexibility
What we provide | Why micro-inverter

Micro-inverter
DC voltage < 40V DC voltage > 600V
String inverter
In PV system consisted of micro-inverters, the voltage at DC side is less than 40V, will not cause any
risk of conflagrations, while in conventional system of string inverter, the voltage at DC side are always
between 600~1500V, which will highly lead to fire risk due to strong drawing arc and electric shocks

Under 40V DC Under 600V DC
Slight drawing arc, no electric shock Strong drawing arc and electric shock
Conflagrations of PV systems due to heavy drawing arcs caused by high DC voltage

Micro-inverter String inverter
100% 100% 100%
50% 50% 50% 50%
50%
In PV system consisted of micro-inverters, highest power output from each panel can be achieved by modular
lever MPPT from each micro-inverter, while in conventional system of string inverter, due to the cast effect, its
yield of energy is always limited by the panel which gives the weakest performance under various conditions

1,500 thousand tests on DC switching
1 million tests about electrical shocks
Surge and lighting strike test at 6000V
Totally water-proof with grade of IP67
Water-proof and dust-proof design at IP67 grade,
can be normally operated after disposal under
depth of water of 1 meter after one entire week,
thus it can resist all kinds of harsh environments

Hybrid inverters series
Store surplus energy and use it however and
whenever you want with our HY series hybrid
inverters. Increase your self-sufficiency by more
than 80% and reduce your energy bill while
creating an always-available source of power.
What we provide | Hybrid inverter

What we provide | Why hybrid inverter
The major reason of storage for PV is because the PV generation usually does not meet requirement from actual
consumption at certain period during a day. Moreover storage can help to solve uncertainty of PV generation
KW

PV generation
PV consumption
Storage consumption

PV generation firstly supplies power to loads, then to battery
if PV power is less than load, battery will discharge for load
When PV generation is getting strong, the loads and battery
are fully supplied, then residual power will be fed into grid

PV generation stops power supply to loads, then the battery
will discharge its power to loads in order to save electric bill
When energy in battery restored in the daytime is totally
consumed, the grid will charge and supply power to load

Rapid Shutdown Device
When installed with and receiving a "permission
to operate" signal from Hoymiles Transmitter,
HRSD starts proper operation of the PV system.
In case of emergency, the PV system would enter
module-level rapid shutdown mode by simply
disconnecting the AC power of the Transmitter or
using an external initiator, bringing your PV
system to safety in 30s.

Transmitter unit
Hoymiles Transmitter comes with a stand-alone
version and a kit version and is used with HRSD to
complete the Hoymiles rapid shutdown solution.
When paired with Hoymiles rapid shutdown HRSD
and powered on, HT10 sends a "permission to
operate" signal to HRSD, to make PV modules
connected in series and then connect to a string
inverter, thus producing power.
