SmartSolar charge controller MPPT 150/35

EN NL FR DE ES SE Appendix

1. General Description

1.1 Charge current up to 35A and PV voltage up to 150V

The SmartSolar MPPT 150/35 charge controller is able to

charge a lower nominal-voltage battery from a higher nominal

voltage PV array.

The controller will automatically adjust to a 12V, 24V or a 48V

nominal battery voltage.

1.2 Ultra-fast Maximum Power Point Tracking (MPPT)

Especially in case of a clouded sky, when light intensity is

changing continuously, an ultra fast MPPT controller will

improve energy harvest by up to 30% compared to PWM charge

controllers and by up to 10% compared to slower MPPT

controllers.

1.3 Advanced Maximum Power Point Detection in case of

partial shading conditions

If partial shading occurs, two or more maximum power points

may be present on the power-voltage curve.

Conventional MPPTs tend to lock to a local MPP, which may not

be the optimum MPP.

The innovative SmartSolar algorithm will always maximize

energy harvest by locking to the optimum MPP.

1.4 Outstanding conversion efficiency

No cooling fan. Maximum efficiency exceeds 98%. Full output

current up to 40°C (104°F).

1.5 Extensive electronic protection

Over-temperature protection and power derating when

temperature is high.

PV short circuit and PV reverse polarity protection.

PV reverse current protection.

1.6 Internal temperature sensor

Compensates absorption and float charge voltages for

temperature.

1.7 Automatic battery voltage recognition

The controller will automatically adjust itself to a 12V, 24V or a

48V system one time only. If a different system voltage is

required at a later stage, it must be changed manually, for

example with the Bluetooth app, see section 1.11.

1.8 Flexible charge algorithm

Fully programmable charge algorithm, and eight preprogrammed

algorithms, selectable with a rotary switch.

1.9 Adaptive three step charging

The SmartSolar MPPT Charge Controller is configured for a three

step charging process: Bulk – Absorption – Float.

1.9.1. Bulk

During this stage the controller delivers as much charge current

as possible to rapidly recharge the batteries.

1.9.2. Absorption

When the battery voltage reaches the absorption voltage setting,

the controller switches to constant voltage mode.

When only shallow discharges occur the absorption time is kept

short in order to prevent overcharging of the battery. After a deep

discharge the absorption time is automatically increased to make

sure that the battery is completely recharged. Additionally, the

absorption period is also ended when the charge current

decreases to less than 2A.

1.9.3. Float

During this stage, float voltage is applied to the battery to

maintain it in a fully charged state.

When the battery voltage drops below float voltage during at least

1 minute a new charge cycle will be triggered.

1.9.4. Equalization

See section 3.8.

1.10 Remote on-off

The MPPT 150/35 can be controlled remotely by a VE.Direct non

inverting remote on-off cable (ASS030550300). An input HIGH

(Vi > 8V) will switch the controller on, and an input LOW (V < 2V,

or free floating) will switch the controller off.

Application example: on/off control by a VE.Bus BMS when

charging Li-ion batteries.

2. IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS - This manual contains

important instructions that shall be followed during

installation and maintenance.

● Please read this manual carefully before the product is

installed and put into use.

● This product is designed and tested in accordance with

international standards. The equipment should be used for

the designated application only.

therefore that there are no chemicals, plastic parts, curtains or

other textiles, etc. in the immediate vicinity of the equipment.

● The product is not allowed to be mounted in a user accessible

area.

● Ensure that the equipment is used under the correct operating

conditions. Never operate it in a wet environment.

● Never use the product at sites where gas or dust explosions

could occur.

● Ensure that there is always sufficient free space around the

product for ventilation.

● Refer to the specifications provided by the manufacturer of the

battery to ensure that the battery is suitable for use with this

product. The battery manufacturer's safety instructions should

always be observed.

3. Installation

WARNING: DC (PV) INPUT NOT ISOLATED FROM BATTERY

CIRCUIT

CAUTION: FOR PROPER TEMPERATURE COMPENSATION

THE AMBIENT CONDITION FOR CHARGER AND BATTERY

MUST BE WITHIN 5°C.

3.1. General

● Mount vertically on a non-flammable substrate, with the power

terminals facing downwards.

● Mount close to the battery, but never directly above the

battery (in order to prevent damage due to gassing of the

battery).

● Improper internal temperature compensation (e.g. ambient

condition battery and charger not within 5°C) can lead to

reduced battery lifetime.

We recommend installing the the Smart Battery Sense

option in case of larger temperature differences or extreme

ambient temperature conditions.

● Battery installation must be done in accordance with the

storage battery rules of the Canadian Electrical Code, Part I.

● The battery and PV connections must be guarded against

inadvertent contact (e.g. install in an enclosure or install the

optional WireBox M).

3.2 Grounding

● Battery grounding: the charger can be installed in a positive or

negative grounded system.

Note: apply a single ground connection (preferably close to the

battery) to prevent malfunctioning of the system.

● Chassis grounding: A separate earth path for the chassis

ground is permitted because it is isolated from the positive and

negative terminal.

● The USA National Electrical Code (NEC) requires the use of an

external ground fault protection device (GFPD). These MPPT

chargers do not have internal ground fault protection. The system

electrical negative should be bonded through a GFPD to earth

ground at one (and only one) location.

● The charger must not be connected with grounded PV arrays.

WARNING: WHEN A GROUND FAULT IS INDICATED,

BATTERY TERMINALS AND CONNECTED CIRCUITS MAY BE

UNGROUNDED AND HAZARDOUS.

3.3. PV configuration (also see the MPPT Excel sheet on our

website)

● Provide a means to disconnect all current-carrying conductors

of a photovoltaic power source from all other conductors in a

building or other structure.

● A switch, circuit breaker, or other device, either ac or dc, shall

not be installed in a grounded conductor if operation of that

switch, circuit breaker, or other device leaves the grounded

conductor in an ungrounded state while the system remains

energized.

● The controller will operate only if the PV voltage exceeds

battery voltage (Vbat).

● PV voltage must exceed Vbat + 5V for the controller to start.

Thereafter minimum PV voltage is Vbat + 1V.

● Maximum open circuit PV voltage: 150V.

For example:

24V battery and mono- or polycristalline panels

● Minimum number of cells in series: 72 (2x 12V panel in series

or one 24V panel).

● Recommended number of cells for highest controller efficiency:

144 cells (4x 12V panel or 2x 24V panel in series).

● Maximum: 216 cells (6x 12V or 3x 24V panel in series).

48V battery and mono- or polycristalline panels

● Minimum number of cells in series: 144 (4x 12V panel or

2x 24V panel in series).

● Maximum: 216 cells.

Remark: at low temperature the open circuit voltage of a 216 cell

solar array may exceed 150V, depending on local conditions and

cell specifications. In that case the number of cells in series must

be reduced.

3.4 Cable connection sequence (see figure 1)

First: connect the battery.

Second: connect the solar array (when connected with reverse

polarity, the controller will heat up but will not charge the battery).

Note 1: divide all values by two in case of a 12V system and multiply by two

in case of a 48V system.

Note 2: equalize normally off, see sect. 3.8 to activate.

Note 3: any setting change performed with Bluetooth or via VE.Direct will

override the rotary switch setting. Turning the rotary switch will override prior

settings made with Bluetooth or VE.Direct.

On all models with software version V 1.12 or higher a binary

LED code helps determining the position of the rotary switch.

After changing the position of the rotary switch, the LEDs will

blink during 4 seconds as follows:

Thereafter, normal indication resumes, as described below.

Remark: the blink function is enabled only when PV power is

present on the input of the controller.
