1.) Main B attery “M AI N I” (must be co nnected):
○Conn ect the batte ry connec ti ons of the co ntrolle r - (M inus) and + ( Plus) to the 12 V m ain batte ry, obs erving th e co rrect
pola rity and the cr oss secti on o f the cable s (refer to c on nection p lan).
○Neve r operate the c ontroll er w ithout th e battery “ Ma in I” . If the ba ttery is not co nnected , th e unit will n ot delive r a
defi ned output vo ltage.
○In cas e of wrong pola rity of bat te ry I, the int ernal saf et y fuse will b e released. The repla cement fuse s hould hav e th e same
capa city, and it shoul d be of the same ty pe (car fus e) !
Para llel chargi ng of two or se ve ral batte ries of the s am e voltage ( 12 V) is admiss ible. The batte ries are to b e “p arallel ed”
2.) Sola r Panel (mu st b e connect ed ):
Shad e th e panels to m inimize s pa rking dur ing conne ct ion and to av oid damag es d ue to event ual wrong p ol arity.
Obse rv e the cable c ross-se ct ions (ref er to conne ct ion plan) !
If sev er al small so lar panel s ar e used, the y are conne ct ed in paral lel (refe r to c onnecti on plan). Par tial shad in g of the pane ls
resu lt s in averag e higher ca pa city (see c onnecti on p lan).
3.) Star ter Batte ry „ START II“ (Optio n, can be con ne cted):
Conn ect the secon d chargin g po rt to the sec ond batte ry u sing the re d connectio n cable (wi re cross sect ion 1.5 - 2.5 m m² ).
This cable m ay be longe r. In c ase of non- utiliza ti on, this te rminal is l ef t free.
If use d, t he output f or starte r ba ttery II wi ll be working w ith reduc ed voltage an d chargin g cu rrent rat es. Th us, the val uable
sola r power will be s upplied t o bo ard/sol ar batter y I be ing more su itable.
Howe ver, the vehic les start er b attery II w ill be kept i n a co ndition , that starti ng will alw ays be possib le, even in c as e of
long er downtime s and durin g wi nter oper ation.
Conn ection of the n egative p ol e „START II“ is n ot requir ed , if the nega tive pole „ BO ARD I“ is con nected to the
vehi cle body. Depend in g on the leng th of the cab le , it may also b e connect ed t o the commo n negative
conn ection of the s olar cont ro ller or to th e negativ e po le of „BOAR D I“.
4.) Tempera tu re Sensor ( Option, can b e connect ed ):
For au tomatic ada ptation a nd c orrecti on of the cha rg ing volta ge to the bat te ry temper ature (temp erature c om pensati on).
Moun ting:
The th ermal conta ct of senso r an d battery " Main I" (in si de temper ature) shou ld be well. Thus, i t should be s cr ewed down
to the n egative pol e or positi ve p ole of the ba ttery. It is also po ssible to f as ten it at the s idewall cen tre of the ba tt ery casin g.
Ensu re that the ins tallati on p lace is not i nfluenc ed b y any sourc e of heat (mo to r block, ex haust, heat er etc.).
Conn ection:
Conn ect the tempe rature se ns or to the ter minal by me an s of a 2-pole c able (cab le c ross sect ion 0.5 - 1.5 mm² ). The p olarity
and ca ble length is o f no import ance. The solar c on troller r ecogniz es t he sensor a utomati ca lly.
Effect:
The te mperature -depend ent chargin g voltage o f ba ttery I wil l be adapte d au tomatic ally to the bat tery temp er ature.
The te mperature s ensor mea su res the bat tery temp er ature. In c ase of low temp erature s (winter ope ration) , th e chargin g
volt age will be inc reased in o rder to impro ve and acce le rate full c harging o f th e weak batt ery.
Safe ty Mode:
Batt ery Protect ion:
In cas e of too low batt ery tempe ra tures ( -30 ° C for lead ba tt eries or -2 0 °C for LiFePO 4) or too hig h ba ttery tem peratur es
(fro m +50 °C), the ch arging vo lt age will be r educed st ro ngly to saf ety charg in g voltage f or battery pr otectio n (d ependin g on
the ty pe from 12.75 V t o 13.00 V). S af ety mode, L ED "charg e" i s flashin g, but any char ging data b eing record ed hither to w ill
be kep t in memory.
Batt ery chargin g is then int er rupted, b ut the supp ly o f eventua lly conne ct ed consum ers will be con tinued by t he solar
cont roller, and th e battery i s al lowed to co ol down. As so on a s the batte ry temper at ure reach es the admiss ible rang e again,
auto matic charg ing will be c ontinued.
The so lar control ler recog nizes autom aticall y a mi ssing sen sor, cable b re ak or short -circui t of t he sensor l ines, as
well a s unreasona ble measu ring values . In that cas e, i t will swit ch automa ti cally to th e usual cha rg ing volta ge
rate s of 20 °C / 25 °C bein g recomme nd ed by the bat tery manu fa cturers .
