This is the controller I use, great bit of kit for the money and you could add more panels later if you like.
For 150 watts you should have at least a 15amp controller.
This would suit your needs too

Sorry this is the proper link for the 15 amp one

The Victron 75/15 is the one I have. It is good for up to 200W and is very compact.

It's worth mentioning that the Victron mmpt controller also works with the Victron Bluetooth dongle which allows you to see what's happening on your mobile phone

As Above and recommended the Victron BlueSolar 75/15 MPPT Regulator.

we wouldn't install anything else with our solar panels..

As Robert said the Bluetooth option is a nice feature or look at the Victron BMV700s Battery display monitor if you like the idea of an accurate readout display monitor mounted in the motorhome..

As @jamesvanbitz says the battery monitor is a great piece of kit as it gives not only an accurate battery level, but also shows how much power is going to the batteries, from solar for example but also how much power you are using , and how many hours your battery will last based on your current usage.

 

[JimJams]

exactly,

We all look at voltage readings and how many AH we are inputting or drawing but trying to work out exactly how long all this will last in where the confusion comes in.

I regularly use the TTG (time to go) when off grid function as it really gives me a good understanding and idea of how long I can use my appliances within the motorhome, this works especially well when I know the forecast isn't particularly good over the next few days and my solar panels will not be inputting as much as I would want and need to look after my battery bank..

@jamesvanbitz is the bluetooth option for the 75/15 an accurate guide as well, or just a guestimate?

 

[JimJams]

I personally haven't used the Bluetooth option so not aware of the performance. I have the Victron display monitor so as yet never had the need but something I am going to have a play with at some point..

I think Robert has so maybe he may let you know on his experience?

@jamesvanbitz is the bluetooth option for the 75/15 an accurate guide as well, or just a guestimate?

It's accurate in as such as it tells you how much power the panels are producing - BUT that's no guide to the charge state of your battery.
Whereas the battery monitor looks at exactly how much power is leaving or entering the batteries and calculates what's left, and how long your power will last.
Totally different info from the solar charge controller.

Personally I'd go for the battery monitor
Which incidentally works with the same Bluetooth device.
