How to Configure the POW-HVM13.2M Inverter Settings

In this video, we walk you through the complete program settings of the POW-HVM13.2M all-in-one solar inverter — from output source priority and battery type selection to charging configuration, battery equalization, and the Smart Dual Output function, so you can configure your inverter with confidence. The POW-HVM13.2M offers four output source priority modes (SUB, SBU, MKS, USB), five battery type options including LIB 485 for BMS communication, and flexible charging control with up to 160A of combined solar and grid charging current. Settings 41 to 45 unlock the Smart Dual Output function, which automatically turns the main output on or off based on battery voltage or SOC to keep critical loads on the second output running for longer. ______________________________________________________________ ✅ WHAT'S COVERED IN THIS VIDEO: • How to access the program settings (press and hold ENTER) • Setting 0: Reset all settings to default (GOE) • Setting 1: Output source priority — SUB vs SBU vs MKS vs USB • Setting 2: Maximum combined charging current (10–160A) • Setting 3: AC input voltage range — APL (90–280V) vs UPS (170–280V) • Setting 5: Battery type — AGM, Flooded, User-Defined, LIB, LIB 485 • Settings 12 & 13: Battery-to-grid switching thresholds in SBU mode • Setting 16: Charging source priority — SNU, CSO, OSO • Setting 23: Overload bypass function • Settings 26, 27 & 29: Boost voltage, float voltage, low-voltage cut-off • Settings 30–36: Battery equalization for flooded lead-acid batteries • Settings 41 & 42: Smart Dual Output and main output cut-off threshold • Setting 43: Lithium battery BMS protocol (PYLON / PACE) • Setting 44: Grid connection delay • Setting 45: Maximum load on the second output (20%–70%) 📋Key specs: • 13.2KW 220/230Vac output, 48Vdc system • Dual MPPT inputs, max 16000W PV (8000W × 2) • Dual output — Main Output 13200W, Second Output 2640W–6600W • Max combined charging current 160A (solar + grid) • Output voltage selectable: 220 / 230 / 240V, 50 or 60Hz • UPS function, transfer time ≤ 10 ms ❓Frequently Asked Questions: Q: What is the difference between SUB and SBU mode on the POW-HVM13.2M? A: In SUB mode, solar powers the loads first, the grid supplements when solar is insufficient, and the battery is used only when both are unavailable. In SBU mode, the battery supplements solar instead, and the system switches to grid power when the battery reaches the low-voltage warning or the threshold set in Setting 12. Q: Should I select LIB or LIB 485 for my lithium battery on the POW-HVM13.2M? A: Select LIB 485 if your lithium battery supports BMS communication — the inverter reads battery data automatically, and you only need to set the discharge cut-off SOC in Setting 29. Select LIB if there is no BMS communication, and manually configure Settings 26 and 29. Q: What is the maximum charging current of the POW-HVM13.2M? A: The maximum combined charging current from solar and grid is 160A, set via Setting 2. Setting 11 separately limits the charging current drawn from the grid. Q: How does the overload bypass function work on the POW-HVM13.2M? A: When Setting 23 is enabled and the inverter becomes overloaded in battery mode, it automatically switches to grid bypass mode to continue powering the loads instead of shutting down. Q: What does the Smart Dual Output function do on the POW-HVM13.2M? A: Enabled via Setting 41, it monitors battery voltage or SOC and automatically turns the main output on or off, so critical loads connected to the second output keep running for longer. Setting 42 sets the cut-off threshold, and Setting 45 limits the second output load to 20%–70% of rated power. Q: Which BMS protocols does the POW-HVM13.2M support? A: Setting 43 offers PYLON and PACE protocols for lithium battery BMS communication. Select the protocol that matches your battery's BMS. ______________________________________________________________ More Info 👇 POW-HVM13.2M https://tinyurl.com/yxt8m7wt Email: support@powmr.com 👇 Related Videos: 1.
