Home PowerDrive V2 - Germany ** 33+ kWh ** Big Power ++
I have 3 Different UPS's and they all have floating Neutrals (120V versions) So they cannot be neutral bonded to ground as far as I know. So I decided to go to a inverter Charger unit (pip 2424-HS) Works a treat now
******Hi My name is Jason and I have SOCD (Solar Obsessive Compulsive Disorder)*******
Current Powerwall - 1400 Cells 7s200p (modular 40p packs) ~ 12kWh of storage     4x 315W Canadian Solar Panels

Working on the next 7s40p packs     ~2.5kWh

Waiting on 2000 Cells of unused Sony vt4 (2000mah 30A) ~ 15kWh      hehehehehe  More Power
I have the PIP working again. Error 09 is fixed.
Have all IGBT and MOSFET and ESD diodes changed and a few more components.

More information can be found at

There have also more photos to the components and repair.

21700 Cell batteries are being tested.

Let's see what they can do.

For the opus, I first had to design an adapter.

Is ok as the first version but will work on an improved version.
Nice Power 21700 Cell
Today the new power lines are finished 25mm² and 35mm².
Unfortunately only 35mm² fit in the 125A DC fuses.
Would have preferred 50mm² but 35mm² are absolutely sufficient on the spot.

The whole thing is expanded with a copper distributor rail to 10x5mm which is designed for 230A
and to the batteries there are 2x35mm² or 1x50mm² via the 160A breaker.


Nice build. Thanks for sharing. But what is/are "kW/h" ?
Kilowatt per hour? Never heard of such unit.

Kilowatt per hour acutally describes (in a strange way) power.

If you want to express energy (capacity) you need to use Ws or kWh (Wattesconds or kilowatthours).
