mikrotik is a router right? I already have a hardware, I was hoping there is a software that I need. What I need is not too different from what cyber cafe use to use those days that big hotels use to grant access to their networks.

brightk:
mikrotik is a router. everytin is embedded into the router..... what kind of hardware do you have currrently..

easyyoke:
It is a 60A controller. If I use 2s3p configuration, what size of wire will be appropriate to carry 41.58A over a distance of 15m

Edrizz:
Use 10mm cable but if u thinking of adding more in the future, then 16mm cable is ur best bet

luvlyoracle:
Why not just get a higher voc cc. On the long run it would be cheaper and easier
I know powmr 60amps cc is about 150v and about 95k

Experts in the house, If a solar charge controller has a maximum Voltage VOC input of 108v(Even though the spec document further says MPPT Voltage Range = 30-95VDC). What is the best configuration for me to connect 6 identical solar panels with each panels having the following specs. Voc = 39.38V and Isc 13.86A into the charge controller without burning the controller.

HeavenlyBang:
Seconded. High amperage just means considerably higher cable costs, not sure why anyone would want that.

RickyM:
No MPPT has a 100% conversion rate, what charges a battery is current not high voltage so even though MPPT are meant to convert the excess voltage to current it’s not a 1:1 thing as there is nothing like a perfect system.

Compare this, the first pix is high voc mppt inverter, the lower one is low voc mppt inverter. Same panels, the low voc mppt inverter was upgraded to the newer high voc inverter. Under similar conditions, the newer one generate more solar power, runs cooler and more efficient. The newer one has its own disadvantage, but as regards solar generation it's better than the low voc inverter

twinskenny:
The bigger one outside are 2hp each running on inverter compressor

Good evening, a JJC here. I just installed a new system which has a 15kwh Felicity lithium battery, 10kva Felicity inverter, 120amps Felicity MPPT charge controller with 12 550watts Canadian Cells Solar panels (the engineer connected them in 3 series of 4 panels). However, the PV numbers I am getting doesn't add up (maximum of 700-800 at peak sunlight) and i can confirm this because it takes an average of 3-4 bright days (without using the system at all) to fully charge the battery. I have an old system with 12 300 watts panels and more than 2kw PV at peak sunlight from that one. I have called the engineer and explained this to him but he hasnt said anything meaningful. Please, are these numbers normal all theres obviously something wrong with his connection? Below is a screenshot of the MPPT readings around past 4pm on a bright sunny day.

HeavenlyBang:
800w from a 6600w array is diabolical. You should be getting 5000w+ at peak irradiance.

APPRECIATION POST

I’d like to express deep gratitude to the folks going out of their way to support and help people on here. Thank you!!

Most especially I’d like to deeply thank @Dam5reey for his guidance, hours of answering questions and even sharing his contacts and providing a transparent process despite not even being the one to assemble or install the system. You are a true reflection of what this space is about and I definitely will be referring my connections to you.

I’m happy to say my mum is now enjoying a 4.2kw solar inverter system with more than enough allowance for her daily needs. We went with the smaller 100A 12v LFP batteries for now due to budget constraints and it’s been working really well so far.

Again, thank you @Dam5reey! 🙏🏾🙏🏾

oga 12v system n ur inv de show 24v?

Peterlove11:
Is that a charge controller or is that the interface of your inverter displaying battery voltage, pv generation?. Be certain if your panels are connected to your inverter or a standalone Charge controller. Then check for the peak generation around 12pm to 2pm with a clear sky. Incase your batteries are full, put a brief load of about 4kw and see if you get close to 4kw or more instantaneous yield. If not, then you need your installer to run a check on your system.

btee13:
Once battery is fully charged and u are not utilizing much from ur system, the MPPT would limit what it is receiving for the PV, To know what ur PVs performance are like turn on more load gradually (6Kw) at peak solar time like 12-2pm . Do that if all tins are okay u would definitely have raise in power from CC.
