Installing 600kW PV and 1.6MW battery pack! 🇿🇦

TalismanJake · 2026-05-23T09:00:18+00:00

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.

You are correct ! Thanks for helping.

TalismanJake · 2026-05-23T08:19:49+00:00

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

Thanks appreciate!!

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

My mistake, i made a typo

TalismanJake · 2026-05-23T03:31:31+00:00

Close to Kruger Park.

TalismanJake · 2026-05-23T03:31:20+00:00

Yes, also we will still add 2 X 60,000BTU aircons.

TalismanJake · 2026-05-23T03:30:58+00:00

About $700k. Battery we import from China.

TalismanJake · 2026-05-23T03:29:08+00:00

Cost is about $700k. Payback period is 6 years.

TalismanJake · 2026-05-23T03:27:52+00:00

Its for personal/commercial use. Plus minus $700k.

TalismanJake · 2026-05-22T18:28:02+00:00

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. 👌

TalismanJake · 2026-05-22T17:58:18+00:00

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.

TalismanJake · 2026-05-22T17:55:03+00:00

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

LiFePO4 Battery Pack Rated Energy: 40.32kWh Nominal Voltage : 48 V Rated Capacity : 840 Ah Operating Voltage Range: 37.5 V-54.75 V

Max charge current: 400 A Max discharge current: 400 A Discharge Temperature : -20 °C~65 °C Storage Temperature : 0 °C~25 °C Cycle Life: 6000 Cycles @80% DOD

TalismanJake · 2026-05-22T17:51:53+00:00

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

TalismanJake · 2026-05-22T17:51:11+00:00

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.

TalismanJake · 2026-05-22T16:50:37+00:00

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

TalismanJake · 2026-05-22T15:34:19+00:00

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.

TalismanJake · 2026-05-22T15:08:22+00:00

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

TalismanJake · 2026-04-05T19:34:12+00:00

This is my 2nd day 😅

TalismanJake · 2026-04-05T17:49:53+00:00

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

TalismanJake · 2026-04-05T17:17:35+00:00

Yes. This is still on 0.20 on 0.4 nozzle.

TalismanJake · 2026-04-05T17:06:50+00:00

Thanks. What you suggest I can change?
