The CX series is a sophisticated solar charge regulator family with exceptional features

in this price range. Beside a perfect PWM regulation with integrated temperature

compensation the controllers provide extraordinary display-, programming- and safety

functions. The battery state of charge is clearly displayed with a bar chart, as well as

energy flows from and to the battery and the load status (e.g. overload, load short

circuit). The deep discharge protection function can be set up to three different modes:

voltage controlled, SOC controlled or adaptive (fuzzy logic).

Acoustic warnings are built in, as well as a programmable nightlight function.

The CX also provides a built-in excess energy management function which means that

in combination with especially designed loads (e.g. Phocos Solar Refrigerators/Coolers

SF32E, SF50E) it is possible to make use of excess energy which would be lost

otherwise because of the overcharge protection of the battery. A better utilization of

the solar system is the benefit.

Description of Functionsn The charge co ntroller protects the battery from being overcha rged

by the solar array and from being deep d ischa rged by the loads. Thecharging charac teristics inc lude several stage s which includes auto -

matic adoption to the ambient temperature.

n The charge co ntroller adjusts itself automatica lly to 12V or 24V system

voltage.

n The pushbutton allows switching the load on and o ff.

n The charge co ntroller ca n be prog rammed for lighting applications.

n The controller provides a control output for spec ial loads that makeuse of excess energy, like the Phoco s SF32E and SF50E Solar Refrigera-

tors. Add itiona lly, it has a serial interface which c an be used with anoptiona l interface ada pter (CX-I).

n The charge co ntroller has a number of safety and display functions.

Mounting and Connecting the Charge ControllerThe regulator is intended for indoor use only. Protect it from direc tsunlight and p lace it in a d ry env ironment. Never install it in humid rooms(like bathrooms).

The regulator measures the ambient temperature to adopt the charg-

ing voltage s, therefore it must be installed in the same room a s thebattery.

The regulator warms up during operation. It shall be installed on a non

flammable surface only.

REMARK: Connec t the controller by following the steps described be lowto avoid installation faults.

1

Open the terminal lid.

2

Remove the sc rews from the strain relief and takeoff the strain relief b ridges.

3

Mount the controller to the wall withscrews that fit to the wall material.Use screws with 4 to 5 mm shaft and

max. 9 mm head diameter, nocounter sunk.

Mind that the screws have to carryalso the force applied by the wiring.

Mind a lso the minimum requireddistance to floor and c eiling, this is

nec essary for ventilation reasons.

A DIN Rail mounting plate is availableas an ac cessory (CX-DR2). This allows

mounting the controller on a stan-dard 35mm DIN rail. Use the screwssupplied with the mounting plate to

fix it to the controller.

a.Remove the green terminal block in the

terminal compartment and turn it upsidedown.

b.Mount the exce ss ene rgy signal wires as

shown in the p icture beside.

c.Co nnec t the signa l wires to the excessenergy management input of the a p-propriate loa d (e.g. Phocos Solar coolersSF32E, SF50E)

d.Reconnect the green terminal block to

the CX

Close the terminal lid.

Now you have succe ssfully connec ted your CX

controller.

Grounding the Solar System

Be aware that the positive terminals of the CX controller are connec ted

internally and therefore have the same elec trical po tential. If anygrounding is required, always do this on the po sitive wires.

REMARK: If the CX is used in a vehicle which has the battery negative on

the cha ssis, loads and solar panels connec ted to the regulato r must nothave an electric connection to the ca r body. Otherwise the overcharge

protection, the Low Voltage Disconnect a nd the elec tronic fuse func-

tion of the c ontroller is short circuited.

Starting up the ControllerSelfTest

Recommendations for UseThe regulator warms up during normal operation. If there is insufficientventilation (e.g. in an installation cabinet), the controller limits the solarcharge current to p revent ove rheating.

The regulator does not need any maintenance or service. Remove dust

with a dry tissue.

It is impo rtant that the b attery gets fully charge d frequently (at least

monthly). Otherwise the ba ttery will be permanently damaged.

A battery ca n only be fully cha rged if not too much energy is drawn

during c harging. Keep that in mind, espec ially if you install add itiona lloads.

Display FunctionsIn normal operation mode the c ontroller displays the state of cha rge(available energy) of the battery. Any change o f the state of charge

(SOC) to a lowe r status is additionally signalled acoustically.System c ond itions are displayed as follows:

25x5x3x2x1x

Load Disconnect80%

The percentage c orresponds to the available energy until Low Voltage

Disco nnec t in relation to a fully charged battery.

As long as the solar array supplies enough voltage to cha rge thebattery, this is indicated by up-moving bars alternately to the state ofcharge display.

In normal ope ration the loads can be switched o n and off by pushing

the button. This is indicated in the d isplay:Load

manually ON

Load

manually OFF

Spec ial conditions are shown in the LC display if the Low VoltageDisco nnec t function shuts off the loa d output or in case of various other

error conditions. See section ERROR DESCRIPTION for details.

Low Voltage Disconnect FunctionThe controller has 5 different modes to protect the battery from being

deep discharged:

Mode 1 Disconnec t at 11.4 V (at nominal load current) up to 11.9 V(at no load current). Normal ope ration mode for good bat-tery protec tion.

Mode 2 Disconnec t at 11.0 V (at nominal load current) up to 11.75 V

(at no load current). Mode with lower disco nnection point.Battery is cyc led de eper, this can shorten battery lifetime.

Mode 3 Disconnect at 11.0 V to 12.2 V depending on load current

and p revious charging cycles. This adaptive mode leads to

longer lifetime o f the battery bec ause it allows recove ry ofthe battery by full rec harge. Ma ximum ba ttery life.

Mode 4: Disconnec t at 11.5 V fixed setting. Appropriate if bypass loads

draw current direc tly from b attery.

Mode 5: Disconnec t at 11.0 V fixed setting. Appropriate if bypass loads

draw c urrent directly from battery. Mode w ith lower discon-nec tion point. Battery is cycled deeper, this can shorten bat-tery lifetime.

The controller is preset to Mode 1 from the factory. Use

Programming Menu 2. to ch ange the setting (see back p age).

In case o f doubts which mo de to c hoose, consult your dealer becausethis has to be evaluated depending on the ba ttery used.

Excess Energy Management Function EEMThe controller provides a built-in excess energy management function.This function, in combination with especially designed loads (e.g.

Phocos Solar Refrigerators/C oole rs SF32E, SF50E), allows to make use ofexcess energy which wo uld be lost otherwise bec ause of the over-cha rge protec tion o f the ba ttery. A be tter utilization of the solar systemis the benefit. Also the battery treatment is improved bec ause more

energy comes direc tly from the solar panel instead of the battery. Askyou dealer about available loads that can make use of exce ss energy.

To connect your Excess Energy load with the controller, see picture 8(signal wires).

Nightlight FunctionThe CX controller comes with a sophistica ted nightlight function. It

controls the load output at night and is widely programmable.

There are 2 modes available:DUSK TO DAWN and EVENING/M ORNING. The mode can be selected in

If you want to reset the c ontroller to the factory settings, choose

Programming Menu 9.

Programming lock-outBy pushing the button for 8 sec in normal ope ration mo de the pro-

gramming lock-out is activated to prevent any accidental settings

cha nge . Another 8 sec push releases the lock-out.

General Safety and Usage RecommendationsIntended Use

The charge regulator is intended for use in photovoltaic systems with 12V or 24 V nominal voltage. It shall be used with vented or sealed (VRLA)lead ac id batteries only.

Safety Recommendations

Batteries store a large amount of energy. Never short circuit a ba ttery

under all circumstanc es. We recommend c onnec ting a fuse (slowac ting type, ac cording to the nominal regulator current) direc tly to

the ba ttery terminal.

Batteries can produce flammable g ases. Avoid making sparks, using

fire or any naked flame. Make sure that the battery room is ventilated.

Avoid touching or short c ircuiting w ires or terminals. Be aware that thevoltages on spec ific terminals or wires can be up to double the bat-

tery voltage. Use isolated tools, stand on dry ground and keep yourhands dry.

Keep c hildren away from ba tteries and the charge regulator.

Please observe the safety recommendations of the battery manufac-turer. If in do ubt, consult your dealer or installer.

Liability ExclusionThe manufacturer shall not be liable for damages, espec ially on the

battery, caused by use other than as intended o r as mentioned in this

manua l or if the rec ommenda tions of the ba ttery manufacturer areneglected . The manufac turer shall not be liable if there has been

service or repair ca rried out by an y unauthorised person, unusual use,

wrong installation, o r bad system design.

Opening ca se voids warranty.
