Greetings! I have been using my EG4 18K for a few months now - with AC coupling - and this week I have commissioned my DYI battery made out of 18 x 24V BYD used batteries. After a few tests, I think the configuration is ok-ish. The batteries are LiFePo4 with an average capacity of 2.75-3.75kWh...

Maybe something like this: https://www.batrium.com/collections/kits/products/watchmon-core-k9 (Original idea from this post)

Thank you for your findings! Would you know if there is a way to use multiple BMS' (9!) with a Megarevo?

Awesome! I may be on the right track then. I will look into multiple BMS' and the concept of master/slaves

Greetings! I am looking for hints on the best wiring scenario for 18 x BYD 24V 3kw LiFePo4, to feed a ~10Kw 48V hybrid inverter (RS485/CAN capable). Got these battery modules cheap from Battery Hookup a few months ago and I learned these cells get out of balance very frequently. At this stage...

Hey, do you have a S This is great and very useful info. I am slowly leaning towards the Schneider XW Pro. Very cost effective and the ecosystem is great: PDP (oh, I would get one of this), Battery Monitor, Gateway... I tried reading through documentation I found on Schneider XW Pro and AC...

I am not doing it yet. Have an old charging station I bought in 2017 which I will replace soon with one of these below. Option 1: Emporia EV charger paired with the Emporia Vue (a power consumption monitor - there is a more expensive version that has 18 CT's o plug in directly to your loads/MSP...

I guess Oh, I didn't know this was possible!: "When the grid is up, any excess production that does not serve the loads or charge the batteries is exported through the pass through port on the hybrid and goes through the MSP". This pass-through seems like a functionality that simplifies a lot...

hmmm, interesting. That's a simpler setup than the one I have been thinking... How does your EVSE get solar from the backup loads if it's connected to the MSP? I was planning to have my solar and inverter grid in connected to at the MSP. In normal use, the inverter would see only source which...

Thanks for the insight! This is definitively very helpful. I am seeing now how much expensive and limited the SolArk's are. I'm not a prepper but would love to be net 0 in electricity (use grid as backup). The Schneider is definitively a nice piece. I watched that video comparing 2 Schneider...

How big is your Schneider XW Pro? Do you have stacking? I found 6.8kw for a single unit to be on the short side for me. If I don't cover our Heat Pump + electric oven + induction cooking in the critical loads, that wouldn't fly with my Miss. Especially when NorCal power cuts are during heat...

If it can speak MQTT, I'm sold! Thanks for the tip

After a few months of having my IQ7 's up and running, I am ready to go phase 2: attach 36kwh of BYD batteries. I want to be ready for Public Safety Power Shutoffs, be net 0 (cover loads at night), charge my EV (another one coming soon) with solar. And for that I have been contemplating the...

Hi David. Just a thought, but have a look at my setup (recent post). It may give you some ideas...? I am still trying to figure out some kinks. Something to think about is that your solar production will shutdown when grid is off. Consider using an ATS switch to automatically (or manually)...

Greetings from Mill Valley, CA. I bought a 6kw solar panel kit from GoGreen Solar a while ago and it's running as it should. Btw, I would recommend those guys: they deliver material + permit docs, you only have to do the work yourself. I have 15 panels + micro-inverters. With solar production, I...
