hi Jeff Cote with specific justices here

we are looking at some Sorel's and your

solar panels will always come out with a

voltage and it's going to even higher or

lower than your battery needs batteries

need to have battery voltage constantly

adjusted to how thirsty they are do they

want to be bulk charging absorption

float so you're gonna want to device

between your solar panels and the

battery and that device is a controller

solar controller when you're buying an

expensive panel and you're buying a

panel that is maybe three times two

times four times five times the cost of

a rigid panel it might make sense for

you to buy what's called an MPPT

controller and in this instance because

we're dealing with a panel that has an

open voltage that is less than actually

12 volts what we're using is what's

called a boost controller from Jennison

really popular we buy these in hundreds

and it doesn't matter if the voltage has

to go up or down at the end of the day

all voltages need to be converted either

up or down to actually charge the

batteries at the right voltage these

little controllers are compact you can

buy them for lithium you can buy them

for light acid you can configure there

for AGM and you can even buy them we're

actually buying them pre-configured at

the factory for the Firefly so you know

on some boats where we're actually

putting Firefly battery banks like we've

got right here we're actually gonna be

by putting a Jennison controller that is

specifically configured for the Firefly

battery really nice super lightweight on

my boat I have three solar panels that

are 50 watt from sodium and I've got

three Jennison GV boosts controllers the

gv8 so if you've got more questions

about these Jennison GV boosts and PPT

controllers contact us at pacific yacht

systems and thanks for watching
