Yes. Mixing panels of different specifications is permitted, but a clear distinction must be drawn between "mixing across different ports" and "mixing on the same port." Provided the input voltage does not exceed the rated maximum, the following guidelines must be observed:

✔️ 1. Across Different PV Input Ports: Allowed

Solarbank 4 E5000 Pro features 4 independent PV input ports. You can connect solar panels with different specifications (power, voltage, or current) to separate PV ports. Each port operates independently, and panels on different ports will not influence one another.

❌ 2. On the Same PV Input Port (Parallel Connection): Strictly Prohibited

It is strictly prohibited to connect solar panels with differing specifications in parallel to the same PV input port. Mismatched parameters will cause reverse current to flow into the lower-rated panels, resulting in degraded energy yield and potential safety hazards.

Configuration Requirements by Panel Count

4 Panels (One Panel per Port): Connect 1 panel directly to each port. Differing specifications across ports have no adverse effect on system performance.

8 Panels (Two Panels per Port, Parallel Connection): The two panels connected to the same PV input port must have identical specifications.

12 Panels (Three Panels per Port, Parallel Connection): The three panels connected to the same PV input port must have identical specifications. Use of the official Anker 3-in-1 Adapter Cable is recommended.
