Pls dat 700 one in the below pix, is it pure sine?

Edit: just checked. Its puresine. Wish i can lay hands on it as it looks like a 12v variant.

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

Brief explanations on my installation
KNIFE SWITCH
Also called a change over, serves two major purposes
1. To change from utility or Gen to inverter and vice versa. Most if not all inverter comes with automatic change over device built into them, at times the supply might be bad and the inverter will refuse to trigger this auto device, in that case the knife switch provides a good opportunity to change over.

Nice one Feflo

Nice one

feflo:
Ongoing installation of 1KWp solar panels at IFO, OGUN STATE.

dragnet:

Looks neat but no rail mounts? how is the panel being held?

Yemmyteespeed007:
hello mr femi.

pls I need and prices for them
solar 12, 200watt
650va ups
charge controller pwm 20amp
battery 12v 100ah, or fearly new 200ah


Are you on whatsapp?

feflo:


I improvised using aluminum rails with bolts, nuts and washers. 4" inches nails are used to fasten the rails on the roof and screws and bolts are used to hold the panels on the rails.

Thanks

dragnet:

That's quite cheaper than the conventional mounts, can I see a picture of the aluminium rails?
what are those white cones? or you coated the bolts with white silicon?

Yemmyteespeed007:
I need the following.

1. 12v , 200wat solar panel
2. Battery 100ah
3. Charge controller pwm 30amp
4. Ups 650va Inverter
5. Solar mounting materials

how much will each cost?

feflo:


24vdc 250watts fairly new solar panel @ 35k
12vdc 100ah brand new battery @ 40k
12/24vdc pwm controller @ 30k
650va converted UPS @ 10k
Solar mount materials @ 4k

Thanks

mctfopt:


I like how you make all these super affordable. Great job

lateefykn84:
how much can I get used 200ah battery
