At Geek,
Clever, but the systems we make, are mostly self sustainable? right?
BUT, when you have a wall of more than ~10kwh on 50 v, it would be wise that a neighbor or family or friend knows what to look for, and how to handle.
Example: if i fall down from the scaffolding and i am 4-6 month hospitalized, i would really like to know what is going on, and instruct that person or my wife.
What if we are both in the hospital...For all i care the whole system goes into a mushroom cloud....But not my pound.
So i will be installing a timer that automatically changes to the grid permanently if i or somebody else does not reset it again after a week or so, and discharge.
With batrium i bought those 48v circuit breakers....its no trick to have a short circuit trip from a timer to the breaker.
A analog timer runs usually for 24 hours but what if you put two on top of each other and set one for one hour off (or two or more)and onehour on.
Or buy a programmable timer that will switch on a light, to trip the breaker after 8 days or 32 days or whatever you want.
The same for my sturgeons, if we are not there for a WEEK the neighbors know what to do(accept vacation), for emergency, and have a phone number for a company that can handle my pond.
The same company will have the option(with instructions) to handle or switch off my pw.
My neighbors also have a phone number ofmy mother andbrotherfor my emercy account ect
My pond is not a carp or goldfish thingy(needs salt ect and i have some red list species with approval!)....the same with the pw i am building....100kwh minimum on 48v(estimed120kwh).....
They are becoming one!
Hope my jibberjat is some good for you, i really understand your concerns, that why the explanation is in the i form, didnt mean to insult you!
With best regards, Igora
