Q:Is this system expandable to 600 or 800 w later on?

by|Jun 26, 2023

1 Answer

Answer This Question

A: Hi Jack - yes, our 400W kits can be expanded to 600W, because the COMET-40 controller can handle up to 600W in a 12V system. You could even take that a step further by upsizing your battery bank to 24V, since this controller is rated for up to 1200W in a 24V system. Each expansion panel will require a branch connector and inline fuse to correctly integrate. Expanding to 800W with a single controller in a 12V system is not possible, since that will exceed the max input rating. However, it is possible to connect multiple controllers to the same battery bank in parallel. Using this approach, you could combine two 400W kits on the same bank for double the charging performance.

Q:Installation for a boat with a 700 amp hour house bank. Will the 40 AMP Charge Controller PWM work ok when I am at the dock and have a hard wired inverter/charger that comes on, or using the generator and the battery charger comes on?

by|Jun 19, 2023

1 Answer

Answer This Question

A: Hi John - Yes, the 40A PWM controller should work in conjunction with any other charging devices. The controller works by sensing the voltage of the bank. If the voltage indicates the bank is less than fully charged, the controller will continue charging, regardless of what other devices might also be connected & charging.

Q:are rubber grommets avaiable for wires?

by|Apr 15, 2023

1 Answer

Answer This Question

A: Hi Marina, It sounds like you are routing cables into a panel or something. We don't provide these parts, but they are readily available at electrical supply distributors and are usually called "Cable Glands". This allows the cable to be supported and retained in the proper place. Thank you, Mike Biron

Very easy installation instructions. Recommend marking positive and negative cables from the solar panels, four panels get a little confusing to hook together. Other than that excellent.

Good stuff

Product is good quality.... panels are very efficient. Unit was easy to assemble.... the only thing I am unhappy with was the very short wire supplied to connect the system to the controller. For a few pennies it would be so much easier if it came with more than ten feet of cable.
