Boss, Selina is here I can confirm that to you.
There is little she can do?
I pray your case will be different.
You may not know what I and others have passed through. One guy whom I believe is here too ordered for his cells from her in June last year and waited till March this year. There is nothing that guy hasn't done to get his good. He finally got tired and ran to Alibaba for refund and I thank God he got his money.
Most of us never knew how tideus and complicated shipping of cells are, neither did we know how careless most of the agents are. We only knew her as we paid for cells and shipment, hoping to receive our goods within the time frame in good condition.
If there is any issue along the line, it's "solely" her responsibility to keep that communication link constantly open to her customers and not to abandon them.
In my case, she left me to my faith when she told me to have patience a month ago that my consignment has issue. Ever since then, she has stopped responding to all the messages I dropped in her box trying to get updates. I was totally confused on where to run to, whom to call and how to retrieve good.
Other members here were the ones talking to her on my behalf as she has stopped talking to me for reasons unknown to me. She still told one of the guys here last week that my consignment has issue with customs unknown to her that my consignment has arrived since.
The local forwarders couldn't trace my good because there was a mixup and it wasn't properly labelled. Out of the four cartons ordered, my name was only written on one carton. I had to pay someone to help me and trace it and I'm very happy it was successful.
I've paid for the shipping again now even as Selina has already been paid and those goods will reach my house today. If she likes, let her eat the shipping fees I've paid to her.
I've moved on as I've also learnt......

He should be getting at least 2.6kw during peak periods.

Try to charge with Solar only, also check maximum solar charge current if it's set to maximum of 80A.
Whats the PV configuration, it looks like 2s4p, if we can see the spec sheet of the panel, it will help determine if he can do 3s or 4s Instead, your friends version can only take max VOC of 145V as stated on inverter.
Also Orientation maybe an issue.

Jefferyzz:
E should not add any panel. Best is for him to bring those panels down n test them one after d other.. something is wrong somewhere. It's either the panels orientation is poor or some of d panels are bad or cable problem.

Very difficult to diagnose solar generation issues without significant information about the system, notes of things can go wrong. Here are the information you should provide.

* What type of battery are they connected to. e.g Tubular or AGM, if possible provide the name or picture.

How are the panels connected, e.g 2 In series (4 in series would damage the inverter solar charger because it would be more than the maximum PV input of the inverter which is at 145v.

* What is the make of the panel, do you have the panel specification sheet (usually the label at the back) where did he get the panels from.

*
What is the distance between the roof (assuming the panels are installed on the roof) and the inverter e.g if the house is an "upstairs" is the inverter installed on the ground floor? this helps to gauge distance. And if possible what type of wiring was done between inverter and solar panel. If you don't know a picture might help.

My preliminary assessment based on what you provided and some assumptions of mine.

I am assuming the Panels are connected 2 in series. If this is the case, the total voltage of the panel assuming VMP is 35v might not be sufficient to charge a 48v battery system when you factor in losses. A 48v battery (assuming tubular) needs at least 57.6v to properly charge. This means the solar panel of 70v would struggle to charge such a battery system when you calculate wiring and heat related losses, in fact they won't much much room for MPPT to happen and this might account for the low charge you are seeing.

If my assumptions are correct and assuming the right wire size is used, then you friend would be best served switching to a 3 in series panel configuration. This would make 2 extra panels redundant. He can stick to using 6 panels in a 3S2P (3 in series, 2 parallel) configuration or buy an extra 400w panel and set them to a 3S3S 3 in series, 3 parallel configuration.

viperVIP:
A little secret here, an engineer in this same company once told me they have a series when loaded beyond 50% of its capacity, would result in overloading.

So I ran for my life

dollarnaira:
Some of us really need basic knowledge on solar/inverter. Without this knowledge you won't go anywhere bc you will keep calling calling calling your installer or anyone who provided assistance. Use google biko.

Just typing inverter online will produce results.

Annoying questions everywhere as if una get answering machine here.

Elcapitan0:

We will find out on cable size and specifications used and communicate. The orientation was not so bad as it was installed on an flat roof. I'll try upload a pics for further clarification.
P.S The sun rises from the other end of the roof and sets on the side of the roof where the panels are.

24v 160ah/12v 320ah lifepo4 lithium battery. made with 100A Bluetooth bms, real capacity brand new grade A EVE 160ah lifepo4 lithium cells with over 4000 cycles!

bigrovar:


This is not really an advantage because DC voltage is not one or constant, if I have a 48v battery system and the inverter freezer is 12v input, I would still need a dc to dc converter to tap into the battery. This only works if your battery system has same voltage as your dc freezer, often times this is never the case.

abuzz33:


Why not put the pricing of your batteries also with the features or is it a secret?

Elcapitan0:

Thanks bro. We don't really know the configuration in which the panels are connected but what i will say is get back to you as soon as we get hold of the installer that mounted the panels for us.We will also do what you advised and get back to you on that. Thanks for your help.

Wagasigiungu:
Hello guys. Pls can I get more information or recommendation on the best and durable dc/ac ceiling fan. I wish to change my home ceiling fans from regular newclime (which I assume consumes up to 75w) to the dc/ac ceiling fans (power consumption of about 25 to 35w I think). This will help save the much needed battery juice.

I don't mind getting any contrary recommendations on how best to maximise the usage of my batteries with fans. This heat no get part two. Lolz

Thanks in anticipation.

Around Q4 last year. I upgraded my solar panels from 9x 335 Yingli panels to 9x 600w Canadian Hiku7 solar panels. Bought panel from techland.

Here is a short performance review.

Installation. The panels are roof mounted with a 21 degree tilt. They face South East at 123 degree Azimuth.

The panels are paired with a 100A / 150v Victron smart solar charge controller. Total capacity is 5.4kw.
9 panels are connected in a 3SP3 arrangements. There is a 10mm2 shielded and UL listed cable between PV and charge controller. Cable length is about 10 meters.

Overall the system performance has been really good. I get an average of 4.5kw output which represents over 80% of panel PMAX.

One thing the panel is really good at is how it handles heat. It has a heat co efficiency of 0.34% and this shows in the performance. Yesterday ambient temperature (as pulled from my personal weather station) was as high as 43C, yet the panel was able to produce (consistently) north of 4400w.

During cloud edge events the panel has produced close to 110% of output which is 5.8kw of 5.4kw PMAX.

I attached 2 centrifugal fans to the Victron solar charge controller to help handle heat since I am using the controller close to it's limits.
