Mercury 3.5HP - how has been your experience with this outboard? I have seen some very BAD reviews around 2011 to 2015 on this outboard, not starting, not running well, etc. I HEARD that mercury had re-designed and copied the much better Tohatsu 3.5HP. Can anyone who has bought this Mercury 3.5HP Four Stroke in the last 1-2 years comment on reliability, use, and "happiness" with the outboard? many thanks, Joao Mendes

Dear Joao, Mercury is a very good manufacturer and thats the reason why we take it in our product range. Please notice the customer ratings below. Your SVB-team.

I have tried to locate information regarding what is best and can only find information that things should be paired. Is it possible to hook up 2 x 140w or 3 x 100w of these panels to 3 x 100ah batteries? Would I then required two charge controllers? Would it be better to isolate the panels 2 x 100w panels - 2 batteries and 1 x 100w panel to 1 battery. And would this also require two charge controllers? Many thanks.

Hi James,
Yes, you can hook up around 300W of solar to 300Ah (3x100 or 2x150Ah) batteries, through a solar regulator. In this setup, it may be best to parallel the panels and use a PWM regulator, at least then if 1 panel is partly shaded, it doesn't impact the performance of the other panels. Alternatively (and not recommending this unless you have a totally out of the shade spot for ALL the panels, like on a Cat), you could connect them in series and use a MPPT regulator which is more efficient at charging than the PWM. However, if one panel is partly shaded, it will significantly bring down the performance of all the panels connected in series.
Hope this helps,
Joao

Since we do not know the exact alloys of the various metals, we recommend the use of plastic washers and bushings for galvanic isolation The SPR110 modules are equipped with back contact cells. For modules with these cells and in the case of high system voltages, there is a risk of potential induced degradation (PID). Then the frame of these modules should be grounded to PLUS via a fuse. The regulator must also be suitable for this grounding type. You must also avoid possible corrosion in the area of the frame's grounding connection. There we recommend the use of Tefgel, article number 61152. For parallel connection of both modules you can use art. 22302. Under optimal conditions, both modules can deliver in sum approx. 12 amps. The cable from Art. 22302 to the solar regulator should therefore have a sufficient large cable cross-section. With each module you receive a 5 m long 2x 2.5 mm² cable. Don't use these cables because the cable cross-section of them is no longer sufficient for 2x 110 Wp parallel connection. Use 6 mm² cable.

I would like to thank everywhere for their help. And especially SVB who were very helpful. Panels work great and because of their efficiency my batteries are fully charge by noon and the size/weight is minimal. Currently using 2 x 110w and will be adding another 110w in the future so I can run more gear.
