Please what is best controller charger & cables to buy- to hook this 100w solar panel into my 1100 watt Krieger inverter & marine deep cycle battery?

There are many brands on the market but we've had a lot of positive feedback on the Victron Energy SmartSolar MPPT charge controllers. They have Bluetooth built-in so from an app on your smartphone/tablet you can monitor the system in detail. With 1x100W panel you could go with the 75/10. If you're thinking of adding more panels you should size a bigger controller. Your panel(s) are going to connect to your MPPT charge controller. Then your controller will connect to your battery bank (via a breaker). This is all DC. Your inverter is separate to the solar and connects to the battery bank to invert DC to AC (probably 110V) In terms of wire size each panel has 17" of 12AWG wire with MC4 connectors built in. Depending on the distance of the wire run you could stay with 12AWG or may have to go to 10AWG for longer distances.

What is the maximum number of these that can be put in parallel?

I believe the maximum number is four. I put three of them in parallel with no problems. Your wires have to be heavy enough to handle the current, and the charge controller must be rated appropriately.

what is the effiency of the panel?

The seller claims they are 23%-25% efficient. There is no way that's true. The most expensive commercial panels are still under 23% efficiency.
