Here's what I see — this is an inverter (3-phase). Here's the diagnosis:
**⚠️ The big picture:**
- Fault code: **ID10 — PV Input Current Unbalanced**
- PV1 & PV2 **voltages are fine** (~736V), so panels are OK
- **But PV1 & PV2 currents are 0A** — no current is flowing from the panels
- Grid: L3 is at 228V ✅ but **L1=4.1V and L2=3.1V** — those two phases are basically dead
- Grid frequency = 0 Hz — inverter can't "see" the grid properly
**Root cause:** The inverter lost two of the three grid phases (L1 & L2). Without stable grid voltage on all phases, the inverter won't connect — and since it's not connecting to the grid, it also won't pull current from the PV panels even though they have voltage.
สรุปคือ dc panel ไม่เป็นไร แต่ไฟ ac ไม่เข้าไปสองเฟส
