Thank you!! How many inches so I know what to buy, if possible the model number? And is that 20 watt on high or low, please?

ThAnks for answering

Good day honorable housemates,

your son is stepping up to 48V system in no time;

and based on user reviews . .i am still undecided on which particular inverter brand(s) to go for except the CC (which will be a 60A Tristar)

so i need personal reviews on inverter brand which would do best at 48V at somewhere around 4kWp panels

Thanks

mcTrinity:


I need price... will need 8-12pcs

thanks

Saipro:


If low budget, the MustPower PowerStar (EP series or VIL) would do fine. I presume you'd be conversant with its idle power consumption and operating temperature bracket of 60^oC to 65^oC.

A Prag would serve almost as well. For mid-range budget, speak with Victron users (local and international reviews look good).

If you would be willing to splurge, Outback (VFX 3048E or the FXR series) or Magnum (MagnaSine series).

Make I check.

I can give two numbers to contact for Gennex directly and no third party

please i need help. i want to power the below load on PV array and on battery backup for 24hrs.
Total Load 1900W
Expected backup time 24hrs if the weather is bad
am using a 3kva/ 48v inverter system


how do size appropriate PV system that can power it
and what is the best connection arrangement- series or parallel

thank you

chidi360:
YOUR LOAD IS TOO HIGH, and your design would gulp over 5m naira, in batts/panels/charge controller etc, confirm you are willing to spend upto 75% of that, so as not to waste anybodys time here .
a simple guide, energy in a 12v 200ah battery is 2400wh, energy you can safely use = 1200wh...... 1200wh can power a 1200w load for 1hr, power 600w load for 2hrs, power 50w load for 24hrs etc

yes am willing to that much.

Am newbie

i have total watthour of 65550wh

divide the wh by 4 to get watts of the panel required for Nigeria on a good day so at least 16.5 KW panels assuming efficiency loss etc at 20 % at least 20 KWp so for 300 watts per panel you need say 66 panels which itself is 4 million approximately


Now remember almost all energy is generated from 9 am to 4 pm ( in 7 hours ) so you need a battery system which can absorb the 10kwh per hour which is 10kwh/50volts = 200 amp . that is atleast 2000 AH 48 V battery bank for flooded or 750 AH for AGM

Plus atleast 4-5 charge controllers of 80 amps


using 3kva 48v inverter system

how many panels do i need assuming i am using 300w PV module?

what connection arrangement can i use?

what size of charger controller do i need?

thank you all

it is easier and cheaper to load shed or change the appliances to energy efficient unless you are running a factory or business which justifies the price premium

ok thanks
please what is the best solar array arrangement to maximum power output. thanks

Here is how to resolve the excessive mustpower series temperature issue by changing the position of the temperature sensor so the fan comes on at 40 degrees vs 65degrees.
step 1: Locate the temperature sensor on the heat sink(first picture)
step 2:Increase the length of the temperature sensor wire by adding additional wires so it can reach the transformer
step 3:Loose one nut of the transformer lamination holder and use a big washer to fix the temperature sensor to the transformer as shown(third picture)

whatsapp me for further clarification(see my signature)
