UPS and Power Inverter:

UPS - UPS or the uninterruptible power supply makes use of an internal inverter to convert DC power to AC. Then it stores power in its built-in battery.

Power Inverter – The inverter is generally connected to an exterior DC source to maintain continuous AC current flow. In this case, a standalone battery or batteries are used for storing energy.

Basic difference:

In UPS, the switchover to backup power is prompt, while in an inverter there is a little delay. This break is acceptable on household appliances like fans, lights, and fridge, but it is not suitable for sensitive equipment like computers and printers. Such delays can cause system crash and data loss.
It uses the main supply line for sending power to various appliances at homes or offices. Unlike the UPS, it is not directly plugged to the appliances.
Technical variance:
UPS – In UPS, the AC from the main power is transformed to DC. This DC is continuously charging the battery. The DC output from the battery is fed to a sine waveform inverter that converts it into AC and supplies it to the equipment.
The energy is regularly drawn from battery, and hence there no gap during the outage on the main. The battery stops getting charged now, but the UPS continues its power supply till the battery gets completely discharged.

Inverter – The main power AC is supplied to the inverter, and it is transformed into DC simultaneously, which keeps charging the battery continuously. There is a sensor and relay structure that always monitors the ON or OFF status of the main.
As soon as there is a power failure, the relay actuator activates the inverter switch. Every other action is similar to the UPS, but because of the sensor and relay process, there is a delay while activating the switch.
Circuitry dissimilarity
Circuits used in making UPS are very expensive than the ones used in an inverter. This is the reason why UPS systems are expensive.
UPS generally comprises:
Rectifier or charger – Rectifier transforms the AC current from the main to DC current, to charge the battery
Inverter – It converts the DC voltage from the battery to AC current, to the electrical equipment
Controller – It regulates the functions of both the rectifier and the inverter.
Inverter comprises:
Inverter – Firstly it converts AC of the main to DC for battery charging. Then it changes the DC power from the battery to AC current, and that flows to the electronic equipment
Controller – It manages the inverter functions

Oga feflo pls can you help me build a rectifier or psu of 14v to 15v?

How much do you sell your solar panel?

turok:
Can I use 20ah battery charger for 1 40ah battery? If yes. How much can you supply the charger?

feflo:


Yes, if it's a smart or regulated charger. The price and supply will come after lock down. Thanks

Based on experience which one is better?
New 100ah battery
Fairly used 200ah battery

So sorry for the late reply. In theory, i will say the New 100ah battery is preferable but based on experience, i will say so may variables needs to be considered before a decision is reached.
1. How long has the 200ah battery been in use, was it abused or well maintained
2. Is the New 100ah battery premium brand or the common china battery
3. Is the Used 200ah battery premium brand or the common china battery
4. What is the weight of both batteries, the New 100ah should be above 30kg and the 200ah should be above 61kg
5. What is the cost of both battery and so many other questions

I sell a lot of Used batteries, if you look at my thread, i call them fairly new because they are always in pristine condition. I also sell New 100ah batteries. This is a very difficult question to answer but if i could get answer to the above questions then and only then will i be able to advise on the better one.

Thanks

Lets look at the same brand e.g new 100ah ritar battery and 60%dod fairly used 200ah ritar battery.
