Hydro system...adding solar

Postby kcebcj on Tue Sep 12, 2017 4:24 pm

Have a 48 volt hydro power system with a Xantrex charge controller and a Outback Inverter System 3600 Watt. The battery bank is a Absolite 48 Volt Gell Pod 350 Amp. The system has been running for 13 years flawlessly. I want to add some solar panels for use during the summer only to possibly run an A/C but am wondering if the system I have would handle the addition. The charge controller is a C40.

This system is off grid. I think the charge controller would need to be upgraded to handle both hydro and solar but just don't know about the Outback Inverter. Just looking for some input from those who know. I appreciate any replies.

Why not keep your existing system and just add solar panels and a second charge controller?

Thanks for the reply.
Yes gonna keep the existing hydro system as I only have 6 months of sun here. Just want to add some panels for summer use and trying to figure what I need to add to the existing system.

Just another charge controller for the panels then into the outback??

Check out this wiring diagram from the Outback FlexMax60/80 charge controller manual:

I take it you are saying I can use a single charge controller with both hydro and solar. Or are you saying there will be two controllers one for hydro and one for the solar then they both dump into the outback and it shoves it to the batteries. No diversion for the solar just the hydro. As you can see this is not my cup of tea. Thanks for the input though.

Yes, two charge controllers, one for hydro, one for solar. Sorry for late response.

Hey Mike appreciate your input.

My hydro system is adjusted to go to diversion at 56.6 volts. So with another controller added for the solar I'm thinking I should set that controller to shut down the panels somewhere before the diversion starts say at 56 volts. Am I on the correct path? Then when the voltage falls below 56 volts the controller kicks in letting the power from the panels go to the battery.

I need to open things up seems to me that there was a voltage setting, when I installed things 13 years ago. that when in the diversion mode the voltage could drop some before it started charging again. So what ever that setting may be, need to set the shutoff point somewhere below that setting or else the panels would go to work below 56 volts just shoving power to the diversion.

This project will be next spring as the sun is almost down to 4 hours in here so have all winter to gather the components so don't worry about the late post.

Check out pages 35-39 of the fm60/80 manual describing diversion load programming. Sounds like it has the features you need: http://www.outbackpower.com/downloads/d ... manual.pdf

Thanks Mike

Been knocking around how I want to set things up. Only need and additional 7-10 amps @ 48 volts during a hot summer. The panels have to be about 200 feet from the inverter. If I use larger panels with higher voltage then would have to use an MPPT controller. If I use 24 volt panels then I get hurt amp wise but could use the cheaper controller.

Anyone have any opinions on a good reasonable MPPT controller? Have looked at the Outback and Xantrex but don't want to spend that much but may end up doing so depending.

Thanks for any suggestions.

Since you have time to think...

Think about it...You want more power but hope to get by without a proven MPPT Charger...

Customer Service and Warranty are paramount for the long haul.

You can Pay now or Pay later...you can decide...

Sparksalot thanks for your concern. I'm not going to "Micky Mouse" the new addition. That PWM Xantrex controller in my existing system I paid 158 bucks for it 13 years ago but looking where I want to install the panels and the distance to the inverter a quality MPPT controller is looking like the only option I have with the panels I want to use.

Thanks to all. Your input is appreciated. There will probably be more question this coming spring when I do the install.
