Patrick Hudon –
Really happy with my new Canadian Solar inverter for my setup. Nice to get something from a Canadian company through Sunmasters – been dealing with them since 2012. Pretty handy that they’ve got an online store now with stuff that’s ready for DIY projects. Works great for folks like me who want to keep things local and don’t mind doing the work ourselves. The CSI-5K model’s been solid so far.
