G'day Kelsey,

You will be able to connect two 120W Solar Chargers together in a chainable system without the regulator to the Rover 100aH. The MPPT controller will be able to handle this as the Solar panels are not always at 100% output and won't overpower the unit. 

G'day Greg,

By all accounts the built-in cooling fan can be pretty noisy.  We don't have the ability to test for decibel level I'm sorry, other than from a mobile phone app in a noisy building, which wont really give you any info at all. 
Ive been intouch with Companion and this information is not provided by the manufacturer at all.  If noise levels are a concern, I'd suggest this may not be the best unit for you.

G'day Chris,

DC to DC chargers are generally only required for smart alternators - so if your vehicle doesnt have a smart alternator or it can be removed in pace of another, then you wouldnt need one.
I was aware that you can turn smart alternators 'off', and not sure if that can be done in a reliable way - eg. not reverting back to 'smart' settings in certain situations, so I would just clarify that with your vehicle manufacturer.  If it's disabled without doubt, you should be fine.

G'day James,

This unit is not really designed to be used with an inverter.

It puts out a maximum of 10A 12v, which equates to 0.5A 240v - generally, this isn't enough to power most 240v devices.
If whatever 240v appliance you have will draw less than 0.5A, you might be ok....in this case you would need a 120-150W inverter.

G'day Josh,

Yeah it can, and does come with all necessary cables, etc.  Only consideration is if you have a smart alternator, in which case you'll need to have a DC to DC charger.

G'day Michael,

Yes technically it can, but given that inverters are inefficient and on average around 10% of power is lost to the inverter, I'd question why you wouldn't just charge via 12v if that's the power source you have.

If you do want to go ahead with charging through an inverter, you be looking at around 1700W min to account for a full capacity charge and the additional 10%.

G'day Jessie,

The solar input on this one is: "Solar Input 18−20V 10A"
Any solar blanket that meets those specs should do the trick, but to simplify you'll be looking at the 180-200W panel ballpark to maximise your charge input.
As this has a built in charge controller, you'll need to bypass or remove the one that comes with your panels, and plug the anderson from the panels straight into the cable for the power station.
you could look at the following options:
Hard Korr Lifestyle 200W
Hard Korr Crocskin 200W
Companion 200W Solar Charger

G'day Mer,

No, you can't.  These are a fully sealed power station, but do have a long life - especially if you care for them well.
If you are wanting an option that allows the battery to be replaced or upgraded, you'd be looking at something called a battery box.
The two options we stock are the Hard Korr and the Engel.

G'day Adrian,

We're not 100% on a lot of the finer details at this stage, as we dont physically have these instock & havent had a chance to play around with them.
We do have a product video coming soon though, and these sorts of questions will be addressed.
Keep an eye on our YouTube Channel or the product page for that in the next few weeks.
