Calculating temperature compensated charging application/pdf English 05.17.2011 1
Read More Download
Tech Note 191.23 Kb pdf

Description:

Here’s a brief explanation on how to calculate the temperature compensated adjustments our controllers make to their charging voltages based on the ambient temperature changes.

The charging voltages listed in the controller operator’s manual are specified at a 25C standard test condition ambient temperature with a -.030V (@ 12V battery) adjustment per degree C change in temperature above or below the 25C reference. The (-) in front of the .030V indicates that voltage adjustment is inverse to the change in temperature. In other words, if the temperature increases above 25C, the controller decreases it’s charging voltage by -.030V per degree C rise above 25C and vice versa. An accurate measurement of the ambient temperature is required for calculating the the controller’s temperature compensated adjustment.

Example:

An ambient temperature of 35C = +10C increase above the 25C base temp = 10 x -.030V compensated adjustment = temperature compensated -.300V decrease in charging voltage.
Therefore, a 14.4V charging voltage specified in the manual @ 25C would be reduced to 14.1V @ 35C or increased to 14.7V @ 15C.

The compensation rate is doubled to .060V/C for 24Vnominal battery systems and quadrupled to .120V/C for 48V nominal battery systems.

Description:

Morningstar controllers have been designed to mount vertically. This is the orientation in which the heatsinks are most effective. Mounting the controller horizontally will reduce its passive cooling efficiency, but the risk of overheating will be determined by the ambient temperature and the power level at which the controller will be operating.

All efforts should be made to mount the controller vertically.

Common Reasons Why Power Transistors Fail text/plain English 09.28.2011 01
Read More
Tech Note 1.00 b txt

Description:

The internal switches of a controller, called MOSFETs or power transistors, switch current on and off to control solar current and load current. Because these components are in the power path, the controller will no longer be able to switch current if they fail.

Power transistors can fail for the following reasons:

  • Over-voltage: lightning or other high voltage transients on the PV power cables.
  • Over-current: too much PV for the controller or a short in the PV line pulls too much currentout of the battery through the controller.
  • Extreme temperatures during charging.
  • A premature failure of the component. The transistors are solid state devices that are manufactured in huge volumes with extremely low failure rates. However, no electrical components are 100% defect free and can pass test and then fail after a short period of time.
  • Old age

DIP Switch Changed Fault (RYG) text/plain English 05.13.2013 01
Read More
Tech Note 1.00 b txt

Description:

If one or more DIP switches are changed while the controller/inverter is powered, the controller/inverter will display a DIP Switch Changed Fault (and the LEDs will begin to sequence). Changing DIP switches while the unit is operating will cause the unit to stop charging until the unit is reset. A reset can be performed by removing power from the device (so that all the LEDs go off) and then re-starting the unit. This procedure prevents the inadvertent changing of operational settings while the controller/inverter is active.

After the controller/inverter has been re-started, it will operate with the new DIP switch settings.

Tech Note 1.00 b txt

Description:

Do Morningstar Controllers regulate according to SOC (State of Charge) calculations?

No. Morningstar Controllers regulate according to battery voltage setpoints. Because battery health and other factors affect charging over time, using voltage setpoints is a way to naturally track these changes and affords the user a complete understanding of the controllers operation. SOC calculations and algorithms may not be precise under all conditions and may leave the user with a “fuzzy” understanding of the workings of the unit.

Tech Note 1.00 b txt

Description:

The note below assumes the meter is powered and displaying text on the screen.

If a button(s) for any one of the following display models appears to stop working:

– TS-M / TS-RM
– TS-M-2 / TS-RM-2
– RM-1

there may be several explanations:

1) You have reached the end of a menu, and there are no more screens to display in that direction (e.g. if you go to the bottom of a menu and continue to push the DOWN arrow, nothing will happen)

2) If the backlight is OFF, the first button press will turn the backlight ON, but will not change the meter screen. E.g. if the backlight is OFF and you would like to move LEFT in the display, you must press LEFT twice – the first to turn the backlight ON, the second to move LEFT in the display). In brightly lit rooms or sunny conditions, it may be difficult to detect whether the backlight is ON or OFF.

3) The button contacts have become dirty. To clean the button contacts:

– Disconnect the meter cable from the back of the meter
– Remove the two screws on the back of the meter, holding the meter circuit board to the faceplate
– Wet a Q-tip or small paper towel with a small amount of alcohol
– Clean the 4 contact points on the circuit board and the contact point on each of the buttons

If the meter button(s) still do not function correctly after checking the points above, contact your Morningstar re-seller / dealer for warranty replacement.

Using a DC power supply as a PV panel substitute? text/plain English 03.05.2009 01
Read More
Tech Note 1.00 b txt

Description:

Can I use a power source other than a PV panel to charge my batteries?

We do not recommend using a DC power supply with any of our PWM controllers. While they appear to be similar to PV modules in function, DC power supplies have considerably more output capacitance. Connecting a DC power supply to our PWM controllers may cause excessive heating and premature failure. MPPT controllers can be used for this purpose without issue. In addition, AC powered battery chargers are often the best option for systems requiring AC battery charging.

What caused my controller terminal to burn/melt? text/plain English 09.12.2014 01
Read More
Tech Note 34.00 b txt

Description:

When two conductors (a wire and screw terminal for instance) are mated, there is a resistance at that connection. Usually this contact resistance is very low and poses no threat. However, when connections become loose, oxidation builds on the surfaces, or corrosion accumulates, the resistance at the connection can increase to a dangerous level.

When current passes through resistance, power is dissipated in the form of heat. If the value of the resistance goes up, so does the power dissipated (for the same amount of current). When a connection has high resistance, the heat generated at the connection can melt surrounding material such as plastics and actually catch fire.

Resistive connections can occur on any electronic device that carries significant amounts of power. It is important to periodically check the tightness of the connections and inspect for corrosion as suggested in the Maintenance section of the Operator’s Manual. Along with periodically checking the connections, dielectric grease can be applied to the terminals to avoid corrosion build-up on the conductor surfaces. Mobile installations tend to be the most susceptible to developing resisitve connections because motion works cables loose from their terminals, however, resistive connections can occur on stationary installations as well.

Direct from the FAQ at http://www.modbus.org :

MODBUS® Protocol is a messaging structure developed by Modicon in 1979, used to establish master-slave/client-server communication between intelligent devices. It is a de facto standard, truly open and the most widely used network protocol in the industrial manufacturing environment. It is literally implemented by hundreds of vendors on thousands of different devices in order to transfer discrete/analog I/O and register data between control devices. It’s really a lingua franca or common denominator between different manufacturers. One report called it the “de facto standard in multi-vendor integration”.

Description:

Other charging sources can be used in parallel with the Morningstar charge controller; you do not need to isolate the controller from the battery. For best performance when using other charging sources, ensure the charging source and Morningstar controller are set to charge to the same (or close) voltage. If the supplemental charging source is set to a higher charging voltage than the Morningstar controller, the Morningstar controller may go into a fault state temporarily when the battery voltage rises higher than the controller’s setpoint. The controller will automatically recover from this state when the battery voltage drops to a lower level.

Wiring an inverter to controller Load output text/plain English 09.28.2011 01

Tech Note 1.00 b txt

Description:

We do not recommend wiring inverters to the load terminals of our products because of current in-rush on start up. Inverters typically have large amounts of input capacitance (for input filtering). When power is first applied, these capacitors can draw very large currents in the 100’s of amps, albeit for a short period of time. These current surges can stress our power transistors and will trip our short circuit protections. The inverter may start eventually after several attempts to reconnect from the short circuit condition, but this mode of operation is not normal. For this reason, we do not recommend wiring inverters directly. Many inverters have their own LVD circuitry and will not allow the battery to discharge too low. However, if the customer requires load control and LVD functionality, they can switch the inverter through a relay wired in series between the battery and inverter.

Wiring multiple controllers to one battery bank? text/plain English 12.10.2007 01

Tech Note 1.00 b txt

Description:

Yes. There can be as many Morningstar controllers as required in parallel on the same battery bank. For best performance, set each controller to as close a charge setting as possible. Since the controllers will not have direct communication with each other, it is not unusual to see the controllers transition between charging stages at different times. This is generally not a concern.
