Awesome, one thing - I haven't delved much into the solar aspect yet. Can you explain what's going on with the way you have the solar panels positive wired to the PCM60X then from the PCM to battery and fused to some input on the PIP? Can you also explain the SHUNT situation you have going on with all the negative wires? Thanks!

Solar panels > breaker > 40m cable > breaker > PCM60X > SHOULD BE A BREAKER > Positive to battery, Negative to INVERTER side of shunt. This is so energy has to go THROUGH the shunt to measure power in and out correctly. it power Comes in from PCM60X and can go directly to the inverter if I had it on the battery side of the shunt it would measure the power going through the shut on the way to the inverter hence giving the 'battery' state of charge a false reading. Does that make sense?

I'd be curious what breakers you're using? I really need to get some for my setup... The only ones I can find either cost $100 or don't work on DC current.

Hi Peter! Thanks for putting out all of the videos. One thing I may have missed or not fully understood is the arrangement of individual packs. Is one 80 cell pack, 1s80p? Then you mount those packs in series to produce 14s80p? That means you're using a 48V system and your nominal pack voltage is about 50V, correct?

Hopefully it's ok to ask about my own build here:
One thing I am looking at doing for my own build is a modular approach in which I can add capacity as I go, starting with one pack and moving forward. This system doesn't really allow that, or am I missing something? What may work better for me is 75 cell packs wired as 15s5p and mounting all finished packs in parallel. Do you foresee any problems with this?

Thanks for the clarification and keep doing what you're doing!

Yes you are correct with mine. Seems to be working for me so far. Your way sounds like it will work well. I guess it all up to you and how you want it to look, how much capacity etc. Good thing about these projects we all learn  Cool

Oi Pete,

Ever thought of adding 3 more banks to the door and 3 banks on the fixed panel holding the door in the same shed??? saves u installing another shed, and ya still got plenty of airflow. U might need to ad more supports to the hindges that suppport to the door or use a star fence picket and hammer it in flush on the on the inside of the doors fixed panel to cater for extra weight and flex.
Be ur own independant self, stop letting the ellites take ur budget.

Hi hbpowerwall,
'
 I watched your latest video, and the new website https://www.batrium.com sounds really fascinating. I like the name and what potential these BMS products hold for us DIYrs'.

Cya,
