Review on 🌞 Valterra Go Power! GP-PWM-30-UL Solar Controller – 30A, Digital, Black by James Mayberry

To upgrade the existing solar system in my 10 year old AS trailer I bought this GP PWM 30 solar controller to replace my old Go Power controller with technology compatible with the conversion It is based on AGM batteries and a new combined inverter/charger 55A Progressive Dynamics (PD4655V) unit with an integrated 4-stage charging converter. The main advantage is the 4-stage charging system, in addition it has a "recharging phase" to "top up" the batteries. It also displays the battery percentage, both numerically and graphically, in addition to the digital readings of the battery voltage and charge current from the old controller. Installation was relatively easy - remove the old block and connect the wires to the appropriate terminals. The slightly larger rear of the device required an enlargement of the wall cut-out, but the screw holes on the front panel corresponded to the original. After the first day, with a "boost", the new batteries showed 100% charge while only the solar panel was used to charge the batteries. To be honest, I was pleasantly surprised to find that despite all the changes that have taken place, this company is still operating. in the solar industry. It might be a bit more expensive than the other options, but it offers the features I need on my system.
