[RE-wrenches] PV panels - ocean environment

Hello, What panels do those of you use who install in a coastal (salt water / air) environment? I recall some panel warranties, such as Sanyo, being voided in a salt environment. Kirk Herander Vermont Solar Engineering 802.863.1202 NABCEP(tm) Certified Solar Installer NYSERDA-eligible Installer V

Re: [RE-wrenches] Trickle charge a generator cranking battery?

David and All Even a 5 watt module will do the task well, as long as the generator digital regulator doesn’t use more than that, and it probably doesn’t. The bleed back thru the module is insignificant in this scenario. Tom Duffy Systems Design Engineer t...@thesolar.biz

Re: [RE-wrenches] Trickle charge a generator cranking battery?

David, Do you have a diode in series to prevent nighttime discharge of the battery thru the module? I have done this for a 100A/H battery with a 16W thinfilm module. I used a series diode, but maybe this is not necessary? See ya! Marv Director of Technology and Support, North America SolarE

Re: [RE-wrenches] Morningstar relay driver configuration help

End results are another thing. I was recently trying to program two RDs to operate six 500W heaters (I needed to use a channel on each as inputs since the battery nominal voltage is 108 VDC). The heaters work off a 5kW inverter. I wanted to keep the battery from exceeding 126 volts since it

Re: [RE-wrenches] Trickle charge a generator cranking battery?

I have been using a 10 watt module without a charge control to charge my generator cranking battery for more than 5 years and i have never had to add water. David David Katz Founder & CTO AEE Solar T(707) 825-1200 C(831) 325-9582 F(707) 825-1202 dk...@aeesolar.com

Re: [RE-wrenches] Trickle charge a generator cranking battery?

Bill: This is an existing, garden variety, sealed cranking battery. I would specify a module that would supply enough charge during winter to keep the battery charged. The battery will have it's own autonomy in that it does not need to be charged every day. If the battery is charged fully o

Re: [RE-wrenches] Trickle charge a generator cranking battery?

William, Wouldn't you want to specify what kind of battery chemistry? How often are you able to inspect this battery/generator system? If you choose SLA battery, will you have consistently good insolation for year round charging? If not, you are saving a bit of initial cost and potentially (q

Friends: Ii it possible, with the correct module, to trickle charge a generator cranking battery without the use of a charge controller? What modules fit this criteria? Thanks in advance. William William Miller Miller Solar Voice :805-438-5600 email: will...@millersolar.com http://millerso

Re: [RE-wrenches] Tar and Gravel Roof Moint

Eric, Locate a reputable roofer experienced with the roof type you are dealing with and sub them to install stand-offs for you, once you determine the array layout. This will save you alot of time and grief, and you will know that the job was done right. Unless you really want to learn the fi
