Is this a good enough setup ?


Recommended Posts



I've been looking at this for a while now.

Looking at the foll setup

  • 8 x 350KW Canadian Solar (4 panels East & 4 panels West)
  • 1 x 5048 Goodwe (toss up between ES / EM)
  • 1 x PylonTech US3000 (initially maybe a 2nd unit when the budget allows)

I did a calculation and I will typically use

Day :1443W per hour (peak of 4543W if I switch on some heavy appliances) with a total of 7618W over a 6 hour day (12 423W if I switch on some heavy duty appliances that day). 

Night : 1367W per hour for about 3 hours, a total of approx 5142W over 12hrs overnight. 

I would like to use some of my battery at night so as to include some energy stored from the day.

Could someone advise if this is possible or am I being unrealistic

The single US3000B Pylontech battery will give you 3200Wh, over 1 hour, or about 1Kw/hour over 3 hours so you're a bit short on the battery capacity. Working with your calculations, you assume that you'll have 6 hour's usable sun light every day. In reality it doesn't work like that. And you won't get the full 2240/hour every hour for 6 hours. In the mornings and afternoons it will be less. Especially if you have 4 panels facing East and 4 panels facing West.

Thank you for your feedback. So I'm aware that this is far from ideal setup and there will be limited supply of energy both day and night. My aim was to introduce some sort of savings and have something for loadshedding

In reality what can I expect from sun generation ?
