Review on 🌞 GP-PSK-40 40W Portable Solar Kit with 10 Amp Solar Controller - Maximize Your Power! by Sam Sergio

For the same price you get 90w compared to the previous 80w kit. Note the DBA/name difference (vs Go Power = GP), these are just Canadian and US subsidiaries of the same company. The controller I received is different (digital/newer?) than the one pictured here on Revain. Buy extended cables to pull the panels around so they follow the sun during the day (if your RV is under trees this is great for the temperature but not the rate at which the panels charge). RV use in Wisco, cloudy days are plentiful and lead-acid batteries charge fairly slowly (that's not the GP's fault, it's the slow charge rate of the lead). Consider upgrading to a lithium battery for faster charging, otherwise happy with this kit. I also called and spoke to their CS team, the representative was very knowledgeable, friendly and helpful.
