Effective Solar Power on My Boat

Some time ago my spouse and i continued holiday for 3 days on the boat. We’ve good leisure batteries along with a decent inverter, so watching television and running the fridge and freezer wasn’t expected to become a problem basically we were away. However, it soon grew to become apparent when we would have liked in which to stay one spot for a couple of days, the batteries would need to be billed by running the engine not less than a few hrs daily. This grew to become a genuine problem since it resulted in i was associated with the boat as the batteries billed. It had been then that people made the decision that solar energy may be the answer.

We did lots of research because we would have liked to complete the job right very first time. The 3 major components needed would be the batteries, the solar charge controller not to mention the solar power panels themselves.

The batteries. Avoid using cheap batteries or perhaps be enticed to make use of so-known as starter / leisure batteries. You have to use proper deep cycle batteries. We chose Trojan viruses T105’s. These batteries are generally utilized on golf buggies. For the reason that application the batteries are billed overnight and used following day round the course. Theses batteries have heavier internal plates than starter batteries and therefore are an ideal option to get together with all of your solar equipment.

The Solar controller. Choose cautiously. Your brand-new Trojan viruses batteries will last a long time if correctly cared for, so purchase a decent controller. We purchased a Victron MPPT 75/15 controller because it may be developed to suit the charging regime the Trojan’s require. MPPT really means ‘maximum power point tracking’. This is an formula contained inside the controller that maximises the creation of the panels to assist fast charging. Cheaper units can fail and damage your batteries.

Solar Power Panels. We’ve three panels, each with a rating of 100 watts. Although nominally with a rating of 12 volts, the particular open circuit current of every panel is roughly 22 volts. We’ve wired them in series as well as in vibrant conditions installed about 66 volts in to the controller. The controller need as much as 75 volts and convey as much as 15 amps. Briefly, the controller changes the input current to AC current then converts it to Electricity current at charging current. Any excess current is transformed into extra amps.

Whenever we first fitted the panels these were fitted flat towards the roof. We realized that people were wasting power by doing this so composed a tilting arrangement to higher align using the sun. This immediately elevated the accessible amperage towards the batteries.

We have been really happy with our solar setup. In summer time the times are lengthy therefore the batteries are charging almost from daybreak. This significantly cuts down on the time spent awaiting the engine to charge the batteries. For more information check out this site.
