PLease is urgent!!!! You can send the manual to dis email : elforra hotmail. Can anyone send me the schematics for that UPS, please? One more time, thanks for the given attention and sorry for the bother caused. Best regard; Pedro Martins. Dutch02 Newbie level 4. Pls send to my private mail to sales. Bosco I need all of document for education Thank you chart jrug thaimail. Any other related information you have will be greatly appreciated as well. Gman82 Newbie level 1. Kind Regards G. However, these guys make a lot of current, and they often charge differently from batteries -- for example they typically charge to the open circuit voltage due to the near zero resistance.
Few times a day System shuts down for very short time seconds - after that wakes up and Color Control indicates that Error 1 then occurs. There is no grid loss then as well. What can be the reason of situation described with words " Device is switched off because one of the other phases in the system has switched off "?
Can it be caused by defective Multi which works properly all day but times a day turn off itself for a while? I am new to this and my system was only commissioned at my holiday house a few weeks ago. My understanding and I may be wrong! Assuming this is correct, is there any way to protect the critical loads from dirty power all the time using the system or does one need a separate stand alone UPS?
Our Victron system is continuously jumping between inverting and bulk and I'm not sure why this is the case. The system was still running fine yesterday, and seems to have started jumping between inverting and bulk somewhere during the evening.
My electricity provider has also already been at the premises to validate that the line voltage is correct and the power quality is supposedly good. I can also hear relays switching each time it jumps between bulk and inverting. Is such frequent switching detrimental to the expected life time of the system, or would it be ok to leave the system running as is? So I guess limit output current to battery to 10A will be fine and not burn up dc power supply nor the PV input which has a max input of 15A I have 7.
With this constelation I have a efficent UPS for 24V devices, battery low discharge protection and a data logger. Is this not nice? When the sine wave is of good quality, the Inverter of the MultiPlus will hook up on it, thus allowing a synchronised and fast transfer when the generator stops. Many generators have more or less ill-shaped sine waves, in particular during sudden load changes. In these situations, the MultiPlus will disconnect frequently or not connect at all.
The UPS function must then be deactivated. The drawback is a slightly longer transfer time. As a start up company, does any suggestion of ups battery? How much voltage and capacity is necessary to buy? I seem to be unable to configure what I was told the EasySolar could do. ESS cannot be started using the Australian grid code it warns that a secondary relay is not present in the product. So nothing does what I want to do. I do not want to feed any power into the grid,..
If there is excess PV power after the batteries are charge and the grid consumption hits zero just reduce the output of the MTTP charger. This is got local regulations compliance The equipment runs through the UPS, but there is no backup when the power supply fails. But if the UPS is off, it will not turn on whilst the color control is plugged in.
Once i unplug the color control, the UPS turns on and power supplied to the server equipment. As shown in that link above I have attached a wall plug to the AC Input and is plugged into a 15A wall socket.
The output is connected to a new output DB board, which in turn connects to my PC and some stand lamps Which we use when we have power outages. My problem is, if I power it up, either in charger mode, or in normal mode it runs for a few minutes and then trips the houses earth leakage.
I will later get it integrated before the houses earth leakage, but for now I just need it to charge the batteries and output through the inverter. I appreciate all answers or pointers to relevant topics in this forum! It is serving as back office for an NGO school project as well as volunteer housing.
It is connected to the grid, with regular occurring power cuts of multiple hours. While the switchover is automatic, we start the genset manually, once the grid is gone. As soon as the grid is back, it is switched back and the genset is idling until we switch it off manually.
In a modernisation of the electrical installation some time ago, we already prepared one circuit in the house carrying all important loads total W…W, occasional W. Now, with some money available we want to add uninterrupted power supply to this one circuit.
The goal is have time before the genset has to be started, possibly not at all during a normal duration power cut of a couple hours in low load situations. If bypass operation is caused by overtemperature, the unit will switch back when the temperature has dropped below alarm level. When the normal situation is restored, the load will be transferred back to the output converter.
The transfer time is less than 4 msecs and is sufficiently short for modern computers, which can ride through milliseconds. If a power failure occurs during bypass operation, the UPS will switch back to inverter and eventually, when the batteries are depleted, output power is lost.
If the UPS functions under overload conditions it may not be able to protect the load. Units connected to battery cabinets will have longer autonomy times. See section 8. Front selectable. Battery start cold start Allows you to switch on the unit while the mains input is absent.
High voltage protection Above the maximum input voltage Vac , the NetPro will protect itself and the load by disconnecting the mains and switching to battery operation. Reducing the mains voltage will recover the normal situation. If the mains voltage rises above Vac the NetPro shuts down immediately and must be restarted manually. Superior battery management for maximum battery life and reliability: - Automatic quick battery test The NetPro UPS conducts automatic battery tests to ensure that the batteries and the wiring are healthy and able to support power failures.
The tests are executed 5 hours after starting up or return of mains, and every 30 days. The tests can also be initiated through UPS monitoring software. During a deep battery test the batteries will be discharged until 'battery low' alarm level.
Please refer to the manual of the appropriate monitoring software package. As a result poor charging of the batteries under low temperature conditions and overcharging of the batteries under high temperature conditions are prevented. This gives maximum capacity without overdischarging. Overdischarging results in failure to recover normal capacity and in shortenend battery life. Load sensing during battery mode prevents unnecessary discharging of the batteries.
The function is default activated front selectable to avoid accidentally switching on during transport. The ComConnect is a plug-in interface port 9-pin, Sub-D, male which enables advanced communication between the UPS and the computer interface kit required. Communication can be done in serial format ComProt or through contact closure interfacing. The electrical interface of ComProt is part of the ComConnect standard.
Relay contacts are available as an option see section 8. The microprocessor controlled and galvanically isolated ComConnect sends information concerning power levels and UPS condition to the computer or network interface. In the event that batteries are near exhaustion, it sends commands for unattended controlled shutdown of the computer system. If the input voltage drops below the set value of the lower limit, the charger output will be reduced to the minimum to prevent further reduction of the voltage.
Also, charger stops at lower limit. UPS Function determines whether the Multi should be critical of the distortion in the supply waveform. To set output voltage of inverter - This is normally Vac. Connection between N and PE during inverter operation. When the internal transfer switch is open inverter mode the Neutral of the inverter is connected to PE. When the transfer switch closes AC input is transferred to the output the Neutral is first disconnected from PE.
To set the low battery voltage level at which the inverter shuts off - To ensure long battery life, this value should be set according to your battery manufacturer specification. To set the voltage at which the inverter restarts after low voltage shut-down. To set the voltage at which the inverter triggers a warning light and signal before shutdown. Note that in fact the parameter which is changed is an offset voltage relative to the DC input low restart level which in its turn is relative to the DC input low shut-down level.
The result of this is that, when changing either one of DC input low restart and DC input low shut-down, this "DC input low pre-alarm" level changes also! Safety Feature - If a short circuit is detected, the unit will not automatically restart unlike other overload conditions.
Energy saving setting to conserve power if there is no significant load drawn from the inverter. Activates Power Assist function. If the load exceeds the AC input current limit the Multi will start inverting in parallel with the external AC supply and will provide the extra current needed.
Note: When PowerAssist is enabled there is a minimum AC input current limit depending on the device type. Setting a lower limit than this minimum will result in the minimum limit.
Note that in a parallel system this limit is per device! The boost factor is the peak power provided by the inverter when the shore current limit is exceeded at start up of heavy loads. This is a safe value because any small peak will be compensated by the inverter and the excessive power will not overload the input circuit protection. Be very careful with this setting and change it only once you have carefully considered the possible negative aspects of doing so!
If the Multi is set to have State of Charge enabled, you can use this feature to shut it down when it reaches the set level. This can be useful on systems where battery voltage does not give a good indication of battery level. The charger page contains all the settings which are related to the charger. For convenience a charge curve is also on this page. This curve changes when the storage mode is changed or when another charge curve is chosen.
This protection can be deactivated for low capacity or poorly regulated power supplies. Stop after excessive bulk Overcharge protection - If the absorption voltage has not been reached after 10 hours, the battery may be faulty and the charger will switch off for safety reasons.
Lithium Battery will trigger battery wizard - This setting will trigger the lithium battery options and wizard, depending on the configuration of your lithium battery and manufacturers advice you may need to adjust additional settings as well.
This is the rest voltage if the battery is fully charged. Special charge curve for traction batteries - For optimum charging, special traction batteries require a fixed charging current phase in addition to a voltage curve.
Beware that this often results in a higher charging voltage that can be damaging to regular on-board consumers! Select charge curve behaviour - Under normal circumstances always select the adaptive mode. If the balance between the charger and battery is not ideal, it may be better to choose fixed mode otherwise the voltage will rise too quickly or too slowly and the battery may be over or under charged as a result.
Manual settings for battery charging - Use this setting to specify the Absorption voltage. Absorption is the charge phase where the battery is held at continuous target voltage with variable current. Float Voltage - Use this setting to specify the Float voltage.
