While somemone close Nordstreams, we deploy Solar UPS “NordStrom 3” recycled Tesla Powered battery pack by EV Clinic. 3D print of the CROBMS and LCD housing is T.S. Custom, Solar panel installation is by Ivan Perić and Victron Energy B.V. Inverters and Mppt.
After 6 months planing, designing and logistics of parts, it’s finally finished, it still has some fine tuning but it passed the Thermal test and Function test at 900 Amps in 2 days.
3x MPPT 250/100
10kWp + 3x 13KW Victron Quattro (15000VA) hybrid UPS
Recycled defective and used 24 pieces (those that pollute the environment in barrels, kebabs, savi, etc.) 24Volt 200Ah Tesla Model S block with a total NET capacity of 105kWh (usable range) and gross 115kWh, in the process of expanding an additional 35kWh 8 blocks (total net 150kWh) Battery system controlled by CROBMS EV Clinic (Made in Croatia) master system in a box as LowVoltage JunctionBox (DVCC, balancing, temp control, 1200A Contactors junction box, overload protection, over temperature, low temp protection, cell imbalance protection, undervoltage protection, short circtuit protection… and 20 more security systems)
The system has 56 temperature sensors and 21312 fuses on the cells and an additional 15 pieces of heavyduty on the busbars.
In addition to the Victron 36kW “baseload” system, at AC OUT1 there is connected ongrid LG panels(it means ongrid to Victron, not hepu) with 10kWp and 10kW 3phase SolarEdge, which shares the LOAD primarily with the consumers of the house and the surplus Victron swallows into batteries (we do not return anything to GRID). .
The third additional booster (aka generator) is the GRID itself, which boosts from the controlled 18kw (overload protection, limiter) through the Victron transformer GRID+Battery so that the basic load rises from the HEP limited 18KW to 54KW, which is a total of 64kW of peak system power.
The system is galvanically isolated from the GRID, adjusted so that nothing is fed back into the network. Surplus from solar is consumed by Bitcoin miner (purchase of BTC network is over 0.13 € per kWh).
The expected life of the battery is an additional 6-10 years, operating conditions and repaired batteries are far milder than in a working vehicle, there are no vibrations, moisture, thermal expansion due to different temperatures and the amperage is lower. 14kw of resistance of the AC system is 340A on the battery, which is equivalent to the power that is on the vehicle about 9.9kW, which means that in some heavy household consumption, the batteries work in twice as easier conditions as on the vehicle. There is no DC ripple and there are no violent amperages like on a vehicle that reach up to 800A. Which means that in order to simulate conditions like in a vehicle, to the power plant (acceleration up to 100 kmh), this system would have to load with 9600A on these 2s12p configurations (12s912p 18650).
The system avoided the extension of the GRID connection from 18 to 30 kw, the request was rejected by governmant, and 27000€ was requested for the extension of the transformer station. Avoided red tariff 0.33 per kWh, lease of excellent power and payment of electricity connection 200€ per kW.
Full investment repayment is 18-30 months with current average consumption of 3000kWh per month and current kWh prices.
Price of the system: energy independence and cheap energy is priceless
64kW three-phase power
22kw of solar panels
150kWh net Tesla battery
This is example why end of life for electric vehicle is no mandatory, every part of EV can be reused again. Even bad and degraded battery can be good for storage system when they are not usable for EV and mobility.
