Search Product Q&A's Answered by Jared, the Generator Expert

Hi Jim - question - what is it that is special about the EcoGen generator for off-grid power versus say the Generac Guardian 8kW Standby. The system is about $1500 more expensive - I recognize that a previous answer you provided online said that having solar makes things more complicated, but there must be something unique about this generator that you need to use it for this application? Can I use the 8kW generator to manually turn on and off back-up power or charge my solar system?
Jeff Brown 
from New York 
April 03, 2014
Answer
The overall engine design and oil lubrication system is much more robust in the EcoGen (5818) system allowing the long term running when paired with a solar systems inverter which will also start the generator will 2-wire control.

The regular 8kW (6237 & 6245) emergency backup standby generators are designed to work with standard applications where utility service is present as the generators internal controller must be connected to utility power to properly operate.

The generator must also be connected to the appropriate automatic transfer switch for proper communication. The connections and controls are not the basic 2-wire start as there are 6 control wires that must be connected to the automatic transfer switch for proper utility service monitoring and generator controls.

The Generac Guardian Home Standby units are not designed, engineered or warranted for use in a solar system.

I have a 9165 watt solar system which reverse meters to the grid. If the power is off, I have no power. Will one of the natural gas backup generators work with my system, or does the solar add complications?
Erik Johnson

Answer
Having multiple power sources can make things very complicated. However, we do offer two models of generators which can be turned on and off by your solar systems inverter system.

Generac's EcoGen model 5818 is specifically designed for use with alternative power options such as solar and wind and comes with a 3 year warranty......

Generac EcoGen Model 5818

Kohler offers their 14kW home standby generator capable for use with solar systems but they only offer an 18 month warranty as they are not specifically designed for this type of application. The generators internal controller can be adjusted to accept a 2 wire start from your inverter system.

Kohler 14kW Model 14RESA

We do recommend consulting with a local installer as your application can have some special parameters and installation requirements. They will also be familiar with your local code requirements so installation is done properly.

I purchased a Generac 5818 LP generator from you a couple months ago. Unfortunately the instruction manual is well hidden or went missing before I got it. How do I go about receiving the installation and operation manual?

Answer
The best way to get access to new manuals is through the Generac website using the serial number from the generator.

Here is the link to access the manuals.....

What is a composite pad ?
CHARLES BLYTHE 
from North Carolina 
April 08, 2011
Answer
The composite pad is a strong, lightweight mounting pad provided to simplify the installation. By including the pad with the generator, installation time and cost is reduced since a concrete base is no longer a requirement.

Is this wireless monitor compatible with the Generac CorePower series ?
Tim 
from New York 
March 01, 2011
Answer
The Generac Nexus™ Advanced Wireless Monitor is only compatible with the Guardian and EcoGen Series models with the internal Nexus™ Controller and cannot be connected to the CorePower model.

Hello Jim, do you have, or can you recommend stand-by generator installers for the Houston, Texas area? We are in the N.W. Houston area.
David Reece 
from Texas 
February 13, 2011
Answer
Since we do not get involved in the installation process and since we ship all over the continental US we do not have a list of installers to provide. You can contact a local Generac dealer who may do installations at a reasonable price and will provide you with the best installation knowledge. You do not necessarily have to purchase a Generac generator from them to utilize their installation and they would be your resource for maintenance and warranty repairs.

Is this generator (Model 5884) a good choice for off grid solar system backup. 14kw not essential circuit?
Avery Edwards 
from Colorado 
January 25, 2011
Answer
The Generac 5884 generator is specifically designed for emergency backup only and will not be warranted in an off-the-grid application.

Generac did come out with a new model specifically designed for off-the-grid and solar applications.
