Hi,
I am planning to build a DIY solar system for my small mining rig:
.
Requirment:
It is a rig with only 8 GPU cards with max 4,100W power requirement, I wish to have it running 24 hours a day, thus it would need 4,100w x 24h = 98.4kWh / day
.
I am do planning basing on and by referring to this video:
.
My place has sunshine hours ranging from 6 hours in Winter to 9.5 hours in Summer, I have some questions:
.
1. For planning, should I use 6 hours of sunshine or to use average say 7.8 hours or to use 9.6 hours for the calculation/estimation?
.
2. Within the maximum W allowed, how will the system (EG448VDC/120VAC Model: UL1741) handle the case when supply W (from solar panels) is greater than demand W (from the rig) at a time?
.
3. Since the batteries are expensive (the most expensive part), how to correctly calculate the number of batteries needed (to be specific, I plan to use EG4 48V 5kWh battery model: UL1973) so to have the rig running 24 hours a day for 365 days a year?
.
Can I use the following estimation?
Total power needed a day: 98.4kWh
Sunshine a day - 6 hours (directly power supply from solar): 4100w x 6 = 24.6kWh
Batteries requirement: 98.4kWh - 24.6kWh = 73.8kWh, thus 73.8 kWh / 5kWh = 15 pcs of server battery (rounding from 14.76)
.
My estimation:
EG4 48VDC/120VAC Model: UL1741 => 2 sets (max 16,000w input from solar panels)
EG4 48V 5kWh battery model: UL1973 => 15 sets
EG4 Server rack: 3 pcs (max 6 server batteries)
Other parts
.
Please help and advise and comment. Many thanks
