How can Shante UPS model MT 1000 continue to supply power for more than 12 hours?

The size of the battery is enough according to the configuration on the second floor, I calculated, theoretically the discharge time is more than 12 hours, but the battery is damaged quickly, with a year or two, the actual capacity may only be about 80%, it is best to let the battery discharge about twice a year, each time you have to release more than 50% of the battery capacity, the battery life is longer.

As for the rechargeable battery connection method, whether the two batteries are connected in series or in parallel is connected according to the DC voltage specified by your UPS. If it is a 12V battery, you now have 2 in series, that is 24V, and after adding 4 batteries, you should connect two in parallel after every two in series. Today's small backup UPS has 24V, 36V and other voltages.

At present, the UPS is displayed by a percentage indicator after the charging is completed, that is, the corresponding charging to the percentage, and the indicator light will be on. There are also liquid crystal displays, there are also charging indicator color change displays, there may also be simpler, that is, only the charging light is on, there is no prompt, but I haven't seen it, the specific is still according to the manual, if not, you can find it on the Internet.

It should be noted that not all UPSs can be loaded for hours with increased battery capacity. Especially the backup model. There are several main reasons for this:

Standard machine (built-in battery) UPS, because the design is only considered to have a short standby time (generally no more than 15 minutes), internal heat dissipation, device margin, wire diameter heating, charging current, etc. If you rush to connect a large battery and extend the backup time, it may cause the machine to burn out. In addition, the internal battery is inconsistent with the external battery, which may reduce the life of the battery, and the external battery life may be greatly shortened because it cannot provide sufficient charging current.

If your printer is laser, you can't bring it, if it's inkjet.

Now you can carry 3 hours of battery, and if you want 12 hours, you need to buy 6 batteries like that.

Need a hand**.

The 2nd and 3rd floors are all good, the most important thing is that the battery capacity should be the same size, and then you have to have an independent charger external.

Friends note that he is MT-1000 and not MT-1000S, so it is recommended that the landlord do not carry out such modifications, otherwise the gains outweigh the losses, thank you!

Buy it a 2 3,195 Ah battery, buy a charger.

One set of batteries is sufficient.

It depends on what the input voltage of your UPS battery is, and we set a group of batteries to be his rated battery voltage.

Generally 12V, 7Ah a battery.

If the input battery voltage is 24V, that is, at least two batteries in series, then we need one group, that is, two batteries are enough.

If it's 48v, that's a set of 4 batteries. Do you know that?

Calculation: 1000*, that is, the rated discharge current is based on the assumption of a power factor of 7ah. That is, it can be used for hours.

This function should be for, i.e. it can bring 15kva*

This refers to resistive loads. Also consider the environment, such as ambient temperature and altitude. The ambient temperature is not higher than 40 degrees. If the altitude exceeds 1000m, it will be derated.

1. Battery box installation: first connect two 12 VDC batteries in series in the battery box to form a group, and lead the positive pole of the group of batteries to one end of the switch, and the other end of the switch is connected to the positive pole of the battery box wiring block, and then open the OFF state, and lead the negative pole of the battery pack to the negative pole of the battery box wiring block.

2. After being accurate, set it to ON state, at this time, the DC gear of the multimeter can measure that the battery box should have a DC voltage of more than 24VDC, and then set the switch to the off state. At this point, the battery box installation is over.

3. Connection between UPS and battery box: After the previous step is completed, connect the positive pole of the battery box and the positive pole of the UPS DC terminal bar with the wire marked + in the random parallel connection wire.

4. The wire marked with -in the connecting line connects the negative pole of the battery box and the negative pole of the UPS DC terminal strip (that is, the UPS is connected in parallel with the battery box), and then the switch on the battery box is set to the ON state.

5. UPS installation: connect the UPS to the mains AC220V. For the requirements of the live wire, neutral wire, and ground wire of UPS input, please refer to the random manual.

6. UPS boot: After the previous steps are accurate, continue to press and hold the power button on the front panel of UPS for one second, you can hear a chirp of UPS, and after a few seconds, UPS green light will be on, at this time UPS has entered the normal working state.

7. UPS test: users can carry out UPS power-off, load and other tests by themselves.

Dear, we're happy to answer your questions. <>

<> if you are using a Sander UPS UPS with a voltage lower than 170 volts, you can try the following methods to turn up the voltage: Check the input power: UPS UPS usually needs to be connected to an external power supply for charging, so you first need to check whether the input power is working.

You can check whether the power plug is firmly inserted into the socket, whether the power cord is in a thick state, whether it is damaged, etc. Adjust the output voltage: Shante UPS uninterruptible power supplies are usually equipped with an output voltage adjustment function, you can refer to the user manual to adjust the output voltage.

In general, the output voltage can be adjusted via the knob on the rear panel of the UPS. Replace the battery: If the UPS UPS voltage is still below 170 volts, it may be because the battery is aging or damaged.

At this time, the UPS battery needs to be replaced, usually by referring to the user's handsail potato book or contacting the manufacturer for replacement. It should be noted that adjusting the voltage of the UPS intermittent power supply requires great caution, and if you are not familiar with the operation, it is recommended to contact the manufacturer or a professional to complete it. In addition, if the UPS UPS voltage still cannot be turned up, there may be a fault in the equipment itself, and the equipment needs to be repaired or replaced.
