Why does Will Prowse suggest not using load
Your understanding is incorrect. Load ports are battery voltage. They vary with the battery. If there is solar available, then the device''s load on the battery, and the subsequent drop in voltage will be compensated for by the solar.

Combining the two DC input ports on these newer power stations?
If you use four 100W panels however, (two on each port to balance the power), the MPPT would accept all of the power (up to the power station''s 400W limit). Again, if the two input ports can be spliced together into one, my three 100W panels in parallel producing 17 amps should work well connected to these two ports that have been combined.

6 FAQs about [Two ports on the side of the solar power supply device]
Which side of a solar PV installation should a supply cable be connected to?
However, on the AC side of a solar PV installation, the PV supply cable shall be connected to the supply side of the overcurrent protective device providing automatic disconnection of supply (ADS) for circuits supplying current-using equipment (712.551.7.2).
Should a PV inverter be connected to a mains supply?
In addition, warning labels should be provided on junction boxes (Regulation 712.537.2.2.5.1 refers). For the purposes of isolation between the mains supply and the PV supply, the PV system should be considered as a load. Disconnecting the AC supply to the inverter will cause the inverter to shutdown.
How does a PV supply cable work?
In a domestic installation, connection of the PV supply cable from the inverter is typically via a dedicated 'way' in a consumer unit, or from an additional consumer unit provided specifically for the PV system and for those essential circuits requiring a back-up supply from the means of embedded generation.
How do you interconnect a PV system to a utility system?
The National Electric Code allows for a few different ways to interconnect PV systems to utility systems. In two editions of Code Corner, Ryan Mayfield with Mayfield Renewables, explains busbar, load side interconnections in 705.12 (B) (3) (1) and (2), and then supply side connections in 705.11 (C) and (D).
How does a PV inverter work?
The AC output of the PV inverter (the PV supply cable) is connected to the load (outgoing) side of the protective device in the consumer unit of the installation via a dedicated circuit (Regulation 712.411.3.2.1.1 refers).
Can a photovoltaic system be used as an additional supply source?
This article will look at a typical photovoltaic installation and highlight the risks that are associated with connecting a PV system as an additional supply source. Photovoltaic (PV) panels are a common sight on the roofs of domestic properties, in towns and cities across the UK.
