Enjoy your investment bro.
Diy or installer?
Congratulations.
Remember that it will serve u if u manage ur consumption well. Dont say "shey b na free sun".

Installer, sofar it serve me all through the night from 4pm till presently, use TV for some hours with all my surrounding lights ON and a DC fan ON all tru the night, just 1bar out from a full battery bar it's already charging this morning and my refrigerator, TV and DC fan is on the battery voltage is at 12.2v but I was advised not to use the battery below 50%, how do I know when the battery bar is at 50% as the battery is not reading in percentage

Based on the voltage of 12.2v it is telling u, that u are consuming power from both ur solar panel and battery ,so u are not charging but taking from the battery. Tubular batteries are tough but improper maintenance and frequent abuse may reduce the lifespan.

Experts in the house, what's your take on solar freezers are they reliable and durable for business please

Not worth it when you factor the high cost, including the cost and challenges of maintenance (getting a repair shop for support etc) all of which drive up the total cost of ownership. The energy difference is not that significant from a conversational Freezer. When you take out the starting current, Freezers are actually energy efficient for what they do, especially the chest freezers. Their ability to withhold cold air allows them to keep things cool for a long time.

You are better up buying a conventional freezer (or even the inverter freezer which Thermocool now sells) and then size up your inverter accordingly.

Good evening house,pls is there any protective device i can get to protect my inverter and solar set up from thunderstorms?

Yes, there and this has been discussed extensively several pages back. You may wish to use the search function.

But briefly, make sure that that your house distribution board has a functioning earth connection and that your ELCB/RCCB trips (you may need to have that checked out by a trained professional). You can also purchase Surge Protection Devices and install them both at the AC side (from NEPA) and on the DC side (from your solar charge controller). Your solar panels on the roof must also be properly connected to your earth system via copper cables to ensure that they are properly grounded and tested. There is a cost to this and the need for a trained professional but trust me it is far cheaper than burnt equipment.

12.0 is roughly 50%.
Check the charging voltage on the sticker of the battery.

If there is no load on it. Den we can say 12v is very close to 50%. But if appliances dey ontop. D real battery voltage might b 12.5 or something. Best is to buy those battery monitor with 4 different wires connected to the shunt. E can b using 1200w discharge level or do the LVD n hvd settings in order to calibrate the monitor SOC.

Congratulations Boss on your setup. The journey of a thousand miles begins with the first step.

My own ideal setup will have been to replace the Solar Panels with (Yingli 450W) which are both high quality and budget friendly compared to these no name chinese brands that eventually start losing capacity quickly. Replace the 1.5kva inverter with the Schneider Homaya and the solar charge controller with a Powmr 60A. Make sure that your panels are connected in series as some kazeem installers can be funny

Tubular batteries like to be charged very well and not be left in a partial state so ensure that your battery is full to the recommended voltage as specified by the manufacturer. Don't be putting heavy loads on the inverter before it is finished charging. Battery is meant for night use so allow the panels to charge the battery well first. Also, check your electrolyte (water) levels regularly and top off with distilled water.

Thought they said mppt controller are better, am using 60a Felicity controller

When I see people advertise these "solar DC freezers" at exorbitant prices, I wonder what's the usefulness since the watts used is similar to an ac freezer minus the starting watts for compressor. I'll even get an inverter ac freezer over the solar freezer as I see no advantage

spot on...I almost made the mistake of getting a DC chest freezer with no surety of after sales or repairs. I just got an thermocool inverter chest freezer and its beings firing over a year now

haarfeez:

The only advantage i can think of maybe some energy efficiency since it is using DC directly, with no multi conversions DC-AC-DC or what have you. But if you are well sized on solar I dont think that should be much of an issue.

Boss how is everything with you? Concerning the bolded, I watched a video somewhere some time ago where a dude built a veery simple circuit called a soft starter. It basically helps to manage that starting inrush current and gently starts up motors. So, I was thinking if that won't be useful for Diyers like us? just a light bulb moment I'm sharing now.

1. Install a lightning arrestor on the electrical system. This device will divert the lightning strike away from the inverter.

2. Install surge protectors on the electrical system. These devices will absorb the surge from the lightning strike and protect the inverter from damage.

3 Install grounding rods around the inverter. This will help to dissipate the electrical charge from the lightning strike, reducing the risk of damage.

Your system is very ok as it is, just stick to the 50% dod rule, don't let your battery be undercharged for too long, check your water level periodically and you are good to go. Congratulations

Ur setup is ok for starter. Did u do all that ursef?

At least the installed used trunk. The things I've seen where the installation looks like olden days NITEL cable lines

nice one, what out for the inverter though the max power it can handle is around 800W - 900W and its idle consumption is not bad 12W

U should be less concerned with the peak power as this is d surge rating. Continuous draw is all that matters. Don't go above 900w as advised.

@osayuwamwen
Dont take the neatness jokes personal o.
Na ppu opinion. Most importantly is the working installation.Once again enjoy your investment as power supply in this part of the world will go very bad soon especially after subsidy removal. I greet you.

Based on the attached at 12.2V it seems you are at 60% DOD.

You would be at 50% DOD if the battery level got to 12.06V.

Hope this helps.

I would have preferred a 1.5kva 24v system to a 1.5kva 12v system.

So please consider upgrading in the near future and please listen to my able brother samir.101ng's suggestions above.

If I may ask, why would you prefer a 24v to a 12v system? 24v means he would need to connect his battery (at least 2) in series. He is using 1 battery for now. So his 12v inverter is in order. He could look at the possibility of upgrading in the future though.

Congratulations, bro. Weldone!

Guys, sorry I need to barge in; I won't be able to read up 1300 plus pages.
Here is my issue.
I have about 12-16hrs public power supply daily but PHED has refused to supply power between 7pm and 12am, forcing me to always put on my gen between those hours.
I want to set up an inverter system that I will charge with public supply to power
A TV SET 75W, A DC FAN 10W, LED BULBS 40W MAX for 5-6 hrs in the evening.
Please what will I need to set this up.
I already got a quotation for a starplus 220ah Tubular battery for 140k (is the battery good and is the price okay?)
Finally, I will build on the system to ultimately power
75W TV, 70W CEILING FAN, LED BULBS 60W, CHEST FREEZER 220W with solar panels as a primary source of power and public supply as back up.
So kindly bear this in mind when recommending an inverter.
Eagerly awaiting your assistance.
Location, Akwa Ibom state.

Agreed.

But he is condemned to less than 1,000 watts draw.

With 24 volts, he can exceed the 1000 watt draw.

Let me refer to a quote online that has put it more elegantly than I am ready to find the words at the moment.
