2 INTRODUCTION Thank you for purchasing the Selectronic Sine wave inverter, model SA41 with ENERGY MANAGEMENT. Your SA41 is a state-of-the-art high performan ce TRUE SINE WAVE DC to AC Power Inverter incorporating ENERGY MANAGEMENT, a unique energy monitoring and controlling system developed by Selectronic to enable you to maximise your lim ited en[...]

3 We suggest that you house your inverter along with other power generating equipment in a rem otely sited purpose built area. Also make sure that the exha ust from your generator or other sources of heat or fumes are kept well away from the SA41. SEIAA (Solar Energy Industries Association Of Australia) installation guidelines must be followed. You[...]

4 Now connect the battery cables: RED = BATTERY POSITIVE (+) BLACK = BATTERY NEGATIVE (-) These connections should be tight. If using nuts, bo lts and washers, they should be stainless steel. At this point re-check the connections before proceeding any further. NOTE: IF THE SA41 EMITS A PULSING BUZZER SOUND, THE BATTERY LEADS HAVE BEEN CONNECTED IN[...]

5 OPERA TION To gain more understanding of these operational notes, it is suggested that they be read in conjunction with hands on access to an inverter with DC power applied. When you first apply power to the SA41 with default factory settings, the SA41 should be in STANDBY mode. There may be a quiet pulsing sound a nd the red neons on the power p[...]

6 READINGS Th e S A 41 ENERGY MANAGEMENT has six "Readings" displays to give you vital information about your inverter and your batteries. By pressi ng the 'NEXT DISPLAY' key on the front panel, the screen information rotates through displays of inve rter Status, Time, AC Volts, AC Am ps and Battery Volts. When the optional curr[...]

7 NETT AMP HOURS TODAY BATTERY CHARGE MINIMUM CHARGE With the optional current shunt (SA-S200) installe d, the m inimum charge in your batteries today, this week or for a number of weeks or days can be logged (Minimum daily discharge). Minimum charge readings are accessed by pressing the UP and DOWN keys together for 1 second. These vital readings [...]

8 SETTINGS There are a number of settings within the SA41 that can be changed via the front panel push keys (push buttons). These allow you to tailor the SA41 inverter and EN ERG Y M ANAGEMENT se c ti on s t o s u it your system requirements. Settings are accessed by holding down the NEXT DISPLAY key for at least 1 second whilst in any "Readin[...]

9 Note that the controller can only be set to LO A/H and CO+LAH if the optional external current shunt kit (SA-S200) is used. Each controller output is capable of switching an external relay or contactor which can be used to switch AC or DC loads. If the controller is set to INV CO , LO A/H or CO+LAH and the condition still exists after the "D[...]

11 LOCKOUT Lockout is a feature which ensures that you are not disturbed during a specified period of time, e.g. you do not want to start a generator in the middle of the night. Wh en set to ON, lockout prevents the controller outputs coming on, or the buzzer sounding during the lockout period. The lockout start and finish times below affect both c[...]

12 AC VOLTS SETTING ALARM INPUTS Th e ENERGY MANAGEMENT has 2 alarm inputs (shown on page s 25 and 26) which can be set to trigger an alarm condition. (See page 15). Use the ‘Lo’ setting if the input is connected to a normally closed set of contacts (see fig 2.1 on page 26), of when the voltage falls below 1V on alarm (see fig. 2.4). Use the ?[...]

14 OVERLOAD SHUTDOWN AND ALARMS The SA41 has eight alarm and overload conditions. Th ese result from high or low battery volts, high AC volts, AC output overloaded, tran sformer too hot, heatsink too hot, either of the two alarm inputs being active, or low battery charge. If any of these conditions occur, a message will be displayed. If there is mo[...]

15 HEATSINK TOO HOT ALARM 1 ACTIVE ALARM 2 ACTIVE LOW CHARGE ALARM F AUL T FINDING 1. INVERTER STAYS ON EVEN WHEN NO APPLIANCE IS BEING USED. This can be a common problem known as a "pha ntom load", but can be easily overcome with ENERGY MANAGEMENT. Some appliances will need to be switched off at the power point as they may still represen[...]

16 3. INVERTER SHUTS DOWN DURING MI DDLE OF THE DAY, AND COMES BACK ON LATE IN THE AFTERNOON. This is more than likely caused by high battery volts during peak charging times from solar panels. To overcome this, adjust the high voltage cutout of your SA41 (see High DC Volts Cutout on page 11); the maximum voltage allowable being 34 Volts. If th is [...]

17 SYSTEM MAINTENANCE To get the optimum perform ance from your SA41 pow er inverter, particularly under heavy appliance loads, it is essential that the battery bank and the DC wiring are all in good condition. The small amount of time spent on the suggested maintenance tasks that follow will maxim ise the reliability of your system. SA41 MAINTENAN[...]

19 RADIO FREQUENCY INTERFERENCE For many years, Radio Frequency Interference (R FI) has been an annoying problem for owners of Inverters. RFI in a domestic situation causes noise or interference on a radio or TV receiver. Most of the problems with RFI in a Remote Area Power Supply (RAPS) installation involve AM radio reception. Considerable develop[...]

20 APPENDIX I: DIAGNOSTICS The "Diagnostics" is a special set of displays that give additional information about the SA41. These are normally only used when advanced troubleshooting is undertaken.
