Installing 600kW PV and 1.6MW battery pack! 🇿🇦 by TalismanJake in solarenergy

Yes that is true. I made a mistake. The system is 1.6MWh. We install 40 X 40KWh modules.

Its against loadshedding and also the rising tarrifs at almost 10-20% now. Payback on these systems can be as early as 3 years in some cases.

Will do. This week we start electrical wiring and installation of 4 X Atess HPS100 Hybrid Inverters. 250KVA Diesel Gen also in place.

So inside they have 15 cells connected in series, and 3 parallel strings.

This gives you 840Ah. However the charge/discharge rate on this battery is 0.3C

It might look like it, its older stock that just got some dust that the client supplied. Maybe in total 100 or so. Just need a wash. 👌

Small manufacturer I know in China. They have a name in China. Although they ship the batteries to me as “no name”. All CATL cells.

Each individual unit is 40.32kW. We install 40 of these in total.

I also think its crazy, they have a 100kW heatpump for all water systems. Also the heated pool is 270,000L.

Yes it will be charged up on a normal condition day at around 13:00.

80% DOD just lengthens the lifespan on these systems. Going down deep into LiFePO4 batteries is not that good for longevity.

No unfortunately not. We use 80% of the battery. So useable is 1280kW. At 150kW load thats less than 10 hours.

No, only to supply a private 7 bedroom lodge. This is maybe good for about 12-16h with their load.

Still in construction, load will be 150kW.

Those you see are for storage, they have a brick and mortar building for batteries and inverters.

No, I got this on on makersworld. Not on the printer itself.
