14. Advantages of 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
Up to 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

15. High security
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

16. No risk of fire
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

17. Higher generation
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

18. Higher efficiency

19. High reliability
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

20. Reliable components
All key components of Hoymiles micro-inverters are totally supplied by top-class brands around the
world, which makes our quality much superior than us, thus we can offer standard warranty for at least
12 years, much longer than the standard warranty from conventional string inverters, for only 5 years
High reliability comes from well-chosen components

44. Why storage for PV?
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

45. Peak shaving & valley filling
PV generation firstly supplies power to loads, then to battery
if PV power is less than load, battery will discharge for load
