Med en peakeffekt på 650 w, og en dagsproduktion på 3,2 KWh, skal du nok ikke regne med og få hverken flæskesteg eller kaffe.
Jeg kan heller ikke se at der er nogen batterier med, så det må jo lede overskudsproduktion up på nettet => Der er kun (Maximalt) 650 w til rådighed, når solen skinner, og kun på 2 faser
Jeg har fået tilbud på et større anlæg med batterier, der burde dække hele mit forbrug.
Jeg spurgte en installatør af solpanneler om jeg måtte sætte det op. Han sagde at jeg bare skulle gøre det, og lade være med at anmelde det. Men om det var lovligt, fik jeg ikke noget klart svar på
Har medsendt nogen af mine spørgsmål til sælger:
Dear Jesper,
Nice week! Thank you for your questions.
Here is our answers:
1. The solar panels are 6,5 KW, but the inverter is only 5 KW. Why ?
For 5KW hybrid inverter, the max. PV input power is 10,000w. Norminal DC voltage =720VDC.
Thus we use 20*325w panels in string to get 720VDC PV array voltage.
2. What are the yearly production?
For 6.5kw solar system, it can produce about 18.33kwh/day=6690.45kwh/year.
So it can 100% meet your need of 4800kwh a year.
3. What are the lifetime on the batteries?
For our lead acid solar battery, our warranty: 3 years and lifetime: 10 years if using dod less than 60%. (dod: depth of discharge)
4. Is the battery capacity sufficient?
For the system, we use 4pcs 12v 250ah batteries. They can have about 9.6kwh battery storage if using 0.8 dod.
Battery capacity and qty can be adjusted based on your storage need.

When we come home from work, we cook, start the washing machine, use the tumbler to dry close, watch tv etc.
Most of our consumption is morning/evening
Here in denmark, we have long days/short nights during summer, and short days/long nights during winter = solar plant will produce more during summertime than winter time.
I dont know wich size solar plant, their makes most sense ?
I also do not know the correct battery size.
Do you supply litium batteries ?
best regards Jesper

Dear Jesper,
Okay, thank you for your sharing info.
If your power consumption is 4800kwh/year, then 6.5KW solar system can 100% meet your demand in both winter and summer.
If you use mostly in morning and evening, then we can increase the battery qty to 8pcs so as to get about 16.8kwh battery backup if using dod =70%. (48V*250AH*2*0.7DOD)
For 6.5kw solar system, it can produce averagely 18.33kwh/day.
For litium battery, we do not supply. Based on we know, litium battery cost is about 3-4 more times of lead acid battery.
And for our hybrid 5kw solar inverter, it can work better with lead acid battery than litium ones.
What's your advice?
Awaiting your reply.
Amanda
