Thanks, I just need one that isn't expensive and does the job really.
There is no free lunch! You've already purchased one cheap controller that you're looking to replace. How much money are you going to throw away before purchasing a decent SCC?
I added 300 watts ($290) to our 170 watt panel and did not have the time to add a second set of cables from the roof to the SCC, because I'd already spent 2 hours traveling to by aluminum, >5 hours fabricating the aluminum roof brackets, >2 hours prepping the roof, >3 hours mounting the panels, a couple of hours rewiring the manufacturers cheap solar wiring (no breakers to the SCC and no breaker out of the SCC), and easily more hours involved. Plus, I'd already spent easily >$150 on proper UV 10 awg wires, breakers, MC4 connectors, and on and on and on.
So I'm NOT going to waste my time invested just to spend money on a cheap controller! I had previously purchased/installed a second Victron 100/20 controller for a portable and found the bus too small for 10 awg wires, but Victron's bluetooth capability and history collection were great. For all that work and expense in the previous paragraph a Victron 100/30 was purchased since it has a proper size bus for 10 awg wires, to replace the cheap GoPower PWM SCC that had no history.
There are good SCC's (Victron, Renogy, etc) and then there is cheap stuff that doesn't work as planned. Spend the money and get something recommended here, since "There is no free lunch!"
Enjoy,
Perry
