The fridge draws more power because you open it frequently and it has normally larger volume with less stored energy ( running at 6-8 deg) versus -14 /-18 of the fridge.

if you use freezer like fridge it will also consume power. Check the nameplates or use power analyser to decide average consumption as every model is different but typically the bigger fridges have much more efficient compressor nowadays

Planning to incorporate a Light Dependent Resistor to the circuit design to switch on the light by night fall and off by day break.
Suggestions please , thanks

davodyguy:

PV connection is different from battery connection.

You're mixing things up.

Just google 'Solar Panel combination' and you get to learn more

From dusk till dawn is about 12hours of light, but varies with daylight savings and soltice. You can use 1 watts or 3 watts high power LEDs in parallel combination of whatever number of chips you intend to use. You can use LED drivers (specific for the number of LED chips series-parallel arrangement) or you can construct simple current limiting resistor circuits as drivers. The 1 watt chips usually have a running current of 350mA, 3 watts chips 700mA while both operate on voltage range of between 3.2v to 3.5v. You may or may not incorporate LED lenses or beam diffusers to widen the beam angle of your lights.

Your choice of power storage could be smf battery (heavier, cheaper) or lithium chemistry based batteries (cleaner, light weight but costlier). You will need CC specific for the battery types you intend to use. Some CC come with dusk till dawn option where they sense the solar power voltage to determine when to output power to the load (lights). In such case, you may not require photocell.

I have tried this before and I wasn't totally satisfied with the set up (due to the limited time I have for leisure from work) so I just went with the simpler options.

For the solar stand alone street lights, I purchased some solar light system from konga and just hardwired a LDR for the dusk-dawn cycle. There is one called "saroda" with 6v 3.5watt panel and 6volt output to two 1 watt bulbs claimed to run for 10 hrs on both bulbs after full charge. The batteries are 2200mah Li-ion in 2s 2p configuration. I modded the power consumption of the lights using limiting resistors to further extend the working time to around 16 hours but with some hardly noticeable reduction in intensity of the lights. The panels are placed on top of each pole.

For the wall security lights, I opted for 12volt DC set up. Got 12-24volt AC/DC powered lights (the 1 watts type consumes around 0.10A at 12volts producing around 100 lumen). It's made with 5050smd LEDs and is bipolarity, meaning it works in any direction you have the polarity. About 10 of such connected in parallel configuration. Dusk-dawn cycle is via LDR. All powered by a portable 12volt 12ah solar system(20 watt poly solar included) which I got off of konga. I recently changed the source to a Li-ion powered set up.

Holy moly! You mean the real deal? As in the "powerwall" or those of the cars? Those would cost a fortune. Will check your videos later.

Guys, thinking through the night, I figured out I simply mistook Watts for Amps! I think it was due to me trying to assimilate too much too quickly in this my old baby steps into the RE world.

My apologies for having disrupted some flow.

Pls house, any review on powerstar w7, 7.5kva,48v inverters? I intend buying one asap, supplier also suggest I get 2 Emerson rectifiers for my 2v 1000ah (24 pcs to make 48vdc) battery bank.

Maybe this one - I have no idea if they stock it. The calendar came with some item I ordered on Konga

@pranil, thanks a million.

I will contact the numbers on the calendar to find out.


Cheers

holy moly,24 units 2v 1000ah, wow that must have cost a fortune..whats the cot per unit?
what is the charging current of the must power?...the 6kva is 40 amps, this i inadequate to charge properly a 48v 1000ah bank, following the C/10 rule, you may get away with this if you dont depelete the bank below 605 dod, or you have solar charging input, as the bank needs to see >100 amp charging current periodically, to avoid sulphation. such battery banks are best fitted with the german/usa inverters, that output >120amps charging current easily...eg the 4kw magnum or schenider is capable of this easily

Oga Pranil, many thanks to your recommendations, I finally pulled the trigger and swapped out my 1hp bedroom AC for a 1hp LG Inverter AC and boy did I make power savings? My net AH removed overnight using the inverter AC in Gen Mode has dropped from 230Ah to about 150Ah - at a reference average voltage of about 50v this is a ~4kwh daily savings.

With the old AC I would reduce target temperature to about 24°C to 25°C and sometimes even use a timer to manage power consumption - with the inverter AC, I set a 16°C target and activate Gen Mode and I'm good to go - if I wake up middle of the night, it is cold enough that I have to set the room temperature warmer so that I and the Madam do not freeze to death

The inverter AC cools a bit different than the traditional AC - one may not get that frosty chill but it is more than cool/cold enough to sleep very comfortably in.

If this performance keeps up, this would be the best purchase decision I made in the month of April 2018.

NiyiOmoIyunade:
Any of the many MustPower brands are decent performers and generally okay brands - they are good for heavy duty loads but are also notorious battery power guzzlers.

You want to be sure you really need a 6kw/7.5kva inverter before you buy one as you are looking at a 230watts per hour no load/idle power draw. Again you have a pretty huge battery bank so inverter self consumption should not be too much of an issue.

As for the DC power supplies or rectifiers as you call them, I would suggest you first install your inverter and see if it has sufficient charging amps (I have measured 50a on some models) to fill up your battery bank within the time frame you desire. Those DC power supplies are rated for like max 53.5volts (unadjusted) and the likelihood is that they would charge for no more than one hour before your inverter has taken the battery terminal voltage above 53.5volts to the point where they shut off - they would only give you any real mileage if you deep discharge your batteries and even then, they tend to reduce charging amps and quickly stop charging altogether when they sense a higher voltage source (your inverter)

Lastly, these MustPower inverters are typically sold as is with not very organised service center or repair help available - should you run into issues, you will be at the mercy of your supplier for a fix or you try your luck with any repairer you can find.

All in all a decent performer and good value for money sha.

This is a very good setup....i can see thousands of naira being spent on this project.....you forget tell to us the PV capacity and the battery bank also the cable size from your PV to the combiner..... Am warming up for my own upgrade as soon as possible....i greet our great men in the house, you are really doing a great job here since the creation of this great and wonderful house. Thank you all.

pranil:

Please let the house know if the supplier product range and prices.

If you get the opportunity also check the price of 8KVA SOL_ARK Hybrid inverter. somebody was just now looking for High power inverter - the EMP capability looks impressive
