Boulder 100i spliced to Yeti 4000 HPP flying leads input
I mounted four Boulder 100i panels on my van, which have the MC4 connections. Wired them together in parallel and penetrated the positive and negative wire ends through the roof. I have the HPP+ input escape remote display adapter, with the Hpp+ to flying leads coming off that and spliced to the MC4 flying leads coming down.
Is this ok? It works, and I do get power from the panels but have only gotten up to 230W so far(from the 400W of panels). Also, when it gets dark and cold, it starts throwing a fault for HV DC In Undervolt. Would this be from the connection I did, or some other issue. I believe I wired everything up with same gauge wire. The panels are connected with two MC4 parallel adapters purchased off amazon.

Not sure if you still need this answered or if you called in.
Here is what I know:
Those solar panels will only produce the rated watts in very ideal conditions including angle to sun, time of day, panel temperature, sky clarity, wire size and length, and more. Read more solar panels here:
The splice and any connections between the solar can also contribute to losses in voltage drop or produce heat as lost power if the connection is loose or if it does not have enough conductive material at any point in the circuit.
Can you send pictures of the setup and connection points? (DM me if you don't want others to see)
The HV DC Undervolt may happen when the solar panel array voltage drops below the low limit set to prevent the Yeti from draining a car starting battery too low which protects your car. Undervoltage at the input will not damage the Yeti. Read more about setup and specs from product pages and user guides:
