Energy Builds: Solis + LG – Part 3: 2nd Battery & Pump Test

I parallel a second LG RESU 16H Prime to the Solis S6 11.4 kW HV hybrid to see if it can finally start my deep‑well pump in inverter/back‑up mode (it worked in bypass). We wire the DC combiner, daisy‑chain RS‑485, set DIP roles (Primary/Secondary), fight through enblock Manager commissioning quirks, flip Solis to LG Parallel = ON, and then run a full pump test—with measurements and the actual fault code. 💲 Use code EASTTEXASSAVE50 for $50 off any purchase over $500 at ‪@SignatureSolar‬ 👉 LG + Solis Bundle: https://signaturesolar.com/solis-lg-b... (affiliate link) What you’ll see • DC combiner box with multi‑tap (Polaris‑style) connectors: #8 from each battery → #6 to inverter • Conduit/gland sizing and spacers for the battery entries • RS‑485 daisy chain (Enable 12 V / GND / A+ / B−) and DIP roles • enblock Manager commissioning for each pack (RMD/BMS/DC‑DC firmware, Wi‑Fi password = RMD MAC + 1234) • Solis Cloud → Local Debug (BT) → Battery Settings → LG Parallel = Yes • Pump test results: inrush ≈ 59.2 A @ 240 V (~14.2 kW), continuous ≈ 25 A (~6 kW) • Fault captured: UNV Backup (Code 1072) → backup‑side undervoltage during start • Why the math says it “should” work (Solis 11.4 kW cont, each RESU ≈ 7 kW cont) yet still doesn’t, and next steps Links (some affiliate) • Solis S6 11.4kW High Voltage Hybrid Inverter → https://signaturesolar.com/solis-s6-1... • LG 16H Prime Battery | 16kWh | 400V | High Voltage → https://signaturesolar.com/lg-16h-pri... • All current links & codes: shopeth dot link → https://shopeth.link • Hardware & tools at Lowe's: https://shoplowes.me/3WmQ2Lz 👉 Part 1 (LG RESU16H install) on East Texas Homestead:    • Energy Builds: LG 16H Prime Install – Part...   👉 Part 2 (Solis S6 install & commissioning):    • Energy Builds: Solis + LG Install – Part 2...   👉 Part 4 (Software fix test — will it finally work?):    • Energy Builds: Solis + LG – Part 4 | Will ...   👉 Part 5 (Voltage test after software tweaks):    • Energy Builds: Solis + LG – Part 5 | Volta...   Notes / Next Steps • DIY at your own risk; high‑voltage DC is dangerous—consult a licensed electrician.
