jFrankNorfleet:
I'd run installation for my gamehouse within the next 2-3 weeks

Pls house I need you to tell me what's wrong with this quote given by my prospective installer. Focus less on the price and more on if the setup will be okay for the gamehouse and how to prevent issues with the setup


These are what the gamehouse would comprise


Lg LCD 32 inches TV 140w *2
Samsung 32 inches led 56 watts *3
Samsung 32 inches lcd TV 110 watts *2
Samsung 15 inches lcd TV 40 Watts *3
PS2 fat 80w 3pcs
PS3 super slim -85Watts 2 pcs
PS3 slim-85 watts 5pcs
PS4 slim 100w 2pcs
Ps5 1 pc 200w
Yokaho DC ceiling fan 40w 1pc
1 duravolt 18 inch standing fan 27w 1pc

Note: I'm yet to get ps5 but it's in the pipeline. Also only 7 out of the combination of 10 PS3, ps4 and ps5 can be operational at once due to limited number of 32 inch TVs




This is what he quoted for me for the above setup

Is there something that should be tweaked for more efficiency?

Hi

I made a quick run based on what you post. Details below:
1. You daily energy consumption is around 20KWH assuming you run all appliances for 12hours with 3days autonomy. This make total battery storage bank higher and oversized.
2. I also did a quick run saving should you use generator and daily fuel purchase of 15000 for like 6-8hrs also assuming you have s 5kva generator to run these thing. see image 2.
3. Image 3 shows the full energy audit result based on your post and benchmark assumptions.
3. From the quote, there are still questions around the cable sizing which are not clear. This is soley for safety reason.
Further more, you can view the full detail report with your exact quote below.https://www.solarspec.com.ng/p/95144d66709a44248fa572a93e62e358bcfbf3f28856331d

Recommendations: I think you should look at the cost savings over a period of time. The major problems of going solar or off-grid is the initial capital. In most cases, the system pays for itself over a short period of time compared to the lower cost enjoyed from running a generator and all other future running cost that comes with owning a generator set.

Lastly, everything i said here are based on assumptions, you might want to request for a proper energy audit from your installer and do not leave anything.

Anyone help with experience with Itel Energy inverter performance and durability.
Considering the 4KW 24v Hybrid inverter.

Can anyone please recommend me any good brand of hybrid invert of this spec ( 24v 3kw-4kw).

What's the best affordable hybrid inverter to buy with minimum of 3.5kva 24v?
Considering you already have a good 24v(2 x 12V 220AH tubular Battery).

NB: One that has good after sales support.

Drgreatone:
That's nice. Use a 2kv12v sms inverter and it's bin doing just fine.
Had issues with the fan always on most of the time when working but recently decided to clean my anti-dust kit. Was so dusty but after cleaning ,fan just comes on occasionally.
2ndly noticed it wasnt always charging my battery well esp when input is around 200-300w (was using 3 300w panels that increasingly looks fake) but then guess thats why its hybrid. I added 2 more (fake)panels to take the pv volt over 150v and it charges better once I'm getting 350w upwards.
Hoping to get original panels to swap the fakes and see just ow well it wud perform

Thanks for this review.
I'm still in the process of deciding which budget friendly Hybrid inverter to buy. And SMS is one of them. Atleast for now.
I'd like to know, does it have monitoring app via Wifi.

Hope to hear from you.

Hello Guyz,
I just needed a professional opinion on this.
I currently have a 12V system with 1000W(4X250) PV in use for about 3years connected to 2 220AH tubular with a 60A CC.
Experience has been good but I'm thinking of upgrading to a Hybrid system. Reasons been that I want to do it in phases myself.
Base on the research in this thread i was able to drill down to the following hardwares:

SMS Hybrid Inverter 2kva/ 2000W 12V (Mppt 80A)
625W X 4 Jinko PV due to space.

However, based on my research, I'm skeptical about the inverter ability to handle the energy from the panel or go the route of upgrading to a 24V system with 120A CC with same amount of panels due to space.

My questions are:
1. Has anyone used that Inverter and whether it can stand test of time.
2. Based on the ratings I've seen for the inverter being 4000W for PV, with it be able to handle future PV addition.
3. Would you advice upgrade the system to a 24V system with 120A CC.

NB: Everything is within a budget and can't exceed but has been prioritized.

All opinions are welcome.
