Question about Tripp Lite PowerVerter APSINT3636VR UPS System

1 Answer

Hi I have a Tripplite 3636VR connect up with 3 X 200AH batteries in series. The inverter works fine when connected to city power, when the city power fails the inverter takes over noramlly, I then go and start a 60KVA generator to power the entire house again, when the inverter starts recieving power from the generator it either switches on and off contonously or trips the incoming circuit breaker on the DB board. Even if there is no load connected to the inverter it still trips the incoming circuit breaker on the DB (Its a 30amp breaker) I have checked incoming power from the generator with a fluke 97 and its fine, frequency is fine too. I am not sure if there are harmonics or not. but it seems to me that there is something wrong with the inverters charging circuit? Can anyone help

Check the system but you may have to turn off the batteries
the inverter is charging the batteries but when mains power fails , the batteries will be discharging back through the inverter that is dc converted back to ac
if you power on a genset and the ac is not phased correctly, what you describe will happen--- inverter ac from the batteries against genset ac to the inverter-
If you had mains power on then it would dead stop the genset because of the out of phase situation
it all has to do with the 2 wave patterns for ac current from each unit being in harmony and not working against each other

SOURCE: No Power when turn on so battery wont charge

Try leaving it off, but plugged into the wall outlet so the batteries can charge up. If they are new, they are probably without a charge. The instructions should indicate how long it needs to charge - probably most of the day.

Hi Godfrey,

Its very difficult to get a circuit diagram indeed. Did an extensive searching . Not sure if this would help you . Please click on the link bellow.

Now once the page opens you would find a number of circuit diagram. You can click on the required image to enlarge it.

SOURCE: The battery backup outlets are not working

You most likely need a new battery. Remove the battery and test it. If you dont have the ability to test it take it to an interstate battery store, or any similar battery store and ask them to test it for you.

SOURCE: i have a ups system that i am feeding with 240 vac

No, I don't think there is anything wrong. Your UPS seems to have a single phase 240V output, which seems to be "floating" (no or only a weak ground reference).
Just be aware that you can only power 240V equipment from it. If you need 120V for some devices _and_ if the UPS provides sine wave output, you could use a step down transformer for this purpose.

SOURCE: Smart2200RMXL2U shows no sign of life after storage

These units, while hot swappable, will NOT start with dead batteries connected.

You will have to replace the batteries to confirm if the unit is still usable. Sealed Lead Acid Batteries do have a shelf life when a charge is not applied and will fail after several months of sitting around.

If your unit was working fine before it was put in storage, I definitely would consider just replacing the batteries. It is possible that the batteries are connected loosely, you can try opening the unit up to double check all the connections but if it has been sitting for more than a couple months, I would definitely consider the batteries dead.

You can find replacement batteries here

My Sukam Inverter is not working, even if the power is on, and its continuously beeping! so how can I direct the power, and so that the switches connected with inverter also works fine?

The first thing I would check is to make sure that the polarity is correct... IE: That you have red connected to positive and black to negative, assuming you're connecting it to a battery that is.

Many inverters will actually self-destruct if the polarity is backwards... But some of the better ones will beep instead.

How do i connect 4 batteries in series

Here is the way to hook them up in series, or in parallel.
There are 3 batteries in top (series) pic, but a 4th would be added in same wiring manner. Disregard the letters "ve" in diagrams, but the +/- polarity is vitally important in hookup.
Note that four 12v batteries hooked up in series will be 48 volts at the end terminals. (If all four are hooked up in "parallel" then the total would still be 12 volts).

If you want to supply a 12v inverter, you need to hook 12v batteries in PARALLEL.

Issues with xantrex dr series inverter

Make sure the battery connection is solid, if the 12 V collapses at the inverter -> no power. If that is OK, make sure to apply first a known good load, like a light bulb, if that still causes a problem the inverter is broken :-(

My Coleman Powermate 2000w inverter gives an error tone when I try to run a 600w space heater. I've tried two different deep cycle new, and even tried them in parallel. The connection...

Assuming there is nothing wrong with the inverter or heater.
You need to check the voltage on the input clamps of the inverter (+ & - connections on the back of the inverter) when going under load, if the voltage is going under 12 volts as it is applying power to the heater there is a connection or volt drop issue.
The inverter is capable of drawing up to 190amps from the battery this can cause damage to the battery.
It is very rare for an inverter of this size to be used on 12 volts.
There are a long list of calculations which I am not going to bore you with, but for this inverter to run on a 12 volt battery system and not cause unesesary damage to the batteries you would need 8 x 120AH deep cycle batteries.

Can this model be used on the grid? If not, is there a sunforce inverter that can be used on the grid?

If you meant for the mains supply then it must be connected in series to the load so that in absence of power the invertor takes over and when there is power the supply takes over as it charges the battery.
So have this wiring done with the connection routed from the fuse box or main board.

Overloaded my inverter -now only works when hooked to car battery

It sounds like the fuse that protects you cigarette lighter is blown.

After you have replaced the fuse, check the voltage again. 0.015vdc would not have powered anything that in manufactured to operate on 12vdc.

When powering anything over about 250W, I would suggest connecting directly to the battery to avoid overloading the lighter circuit.

My tripplite pv375 inverter keeps blowing fuses instantly; with nothing plugged in. any help would be appd.

Sounds like it may have a bad power transistor, it will cost more to fix than replace. What is the story behind the question, last time it was used? Who borrowed it? It may have been overloaded ... $40-$70 should get you a new one.
