1 Safety precautions
iMars series grid-tied solar inverters are designed and tested strictly in accordance with relevant
international safety standards. As an electrical and electronic device, all relevant safety regulations
must b e stric tly com pl i ed durin g ins t all at i on , oper ati on, and mai nt enanc e. Incorrec t use or misuse
may result in˖
z Injur y to t h e lif e and p ersonal s afety of th e op er at or or ot h er peop l e.
z Damag e to t h e in verter or oth er property belonging to t h e operator or other p eop l e.
In order to av oi d p ersonal injur y, damage t o the inver t er or other devices, pl ease stri c t l y observe
the following safety precautions.
This ch apt er mai nly desc ribes various w ar n i n g s ymb ols in operation manu al and provides s afety

2.1 Solar grid-tied power generation system
2.1.1 Applic ation
The photovoltaic grid-tied power generation system consists of solar modules, grid-tied inverter,
metering devices and public grid.
Figure 2.1 Application o f iMars series grid-tied solar inverters
Grid-tied solar inverter is the core of photovoltaic power generation system. The solar energy can
be converted into DC electric energy through solar modules and then be changed into sinusoidal
AC energy which has the same frequency and phase with the public grid by grid-tied solar
inverters, and then be fed to the grid.
iMa rs series grid-tie d solar inverters are only applied in solar grid-tied power generation system
and its DC input are only composed of crystalline silicon solar modules whose negative and
posit i ve p ol es are not gr oun ded.
z The re comme nded sola r modules need to comply
z iMars series grid-tied solar inverters are only for crystalline silicon solar
modules.
2.1.2 Supported grid connection structure
iMars series grid-tied solar inverters support TN-S, TN-C, TN-C-S , TT and IT grid connection.
When applied to the TT connection, the N-to-PE voltage should be less than 30V.

If th e invert er is not p ut into us e immedi ately, the st orage of i nverter s hould m eet the f ollowin g
requirements:
z Do not remove the outer packing.
z The inverter needs to be stored in a clean and dry place, and prevent the erosion of dust and
water vapor.
z The st orag e t emp erat ure s hou ld b e kep t at -4 0°C~ +70° C, and th e r elat ive hu midit y s h ould
be kept at 5%RH ~ 95%RH .
z The st ac ki ng of inver t er s is rec ommen d ed to be placed accord in g to th e nu mb er of st ac k in g
layers in th e origi n al sh ip m ent. Pl ac e the inverter c arefully duri ng st a c king to av oid personal
injur y or equ ipment dam age caused b y the f alli ng of equipment.
z Keep away from chemically corrosive substances that may corrode the inverter.
z Periodic inspections are required. If damages are found by worms and rats, or packaging
are found to be damaged, the packaging materials must be replaced in time.
After long-t erm st orage, i nvert ers need to be ins pect ed and t ested b y qualifi ed pers onnel bef ore

Select installation place based on the following considerations:
(1) Height from ground level should be enough to ensure that display and status LCD are
easy to read.
(2) S elec t a well v entilated plac e sh elter ed fr om di rect sun radiation and rain.
(3) Allow sufficient space around the inverter to enable easy installation and removal from the
mounting surface. Refer to Figure 4.1.
(4) The envir on m ent temperatu r e is between - 25 ć~60ć.
(5) The ins tallat i on p os ition keeps awa y from th e int erface of ot h er electr i c al de vise.
(6) The invert er n eeds t o b e inst al led on a fir m an d sturdy surfac e, suc h as w al l an d m etal

(7) The installation surface should be perpendicular to the horizontal line. Refer to Figure 4.2.
(8) The installation should be ensure that the inverter is reliably grounded, and the material of
grounded metal conductor should be consistent with the metal material reserved for the
groun di ng of the in vert er.

iMars grid-tied solar inverters Monitoring communication
7.1 Standard communication
The standard communication mode of iMars grid-tied solar inverter is RS485 which includes
“RS485-M” and “RS485-S” ports. The RS485-M ports c an com muni cate w ith pr ivate c omput ers,
smart phones and so on. The system monitoring solution is shown as figure 7.1.

Connection steps:
(1) Weld communication cables to the RS485 terminals of the inverter as Figure 7.4 shows.
Ensure the cable corresponds to the pin as table 7-1 shows and the welding is tight
enough.
