Genasun GVB-8-PB-12V-WP-GP, Waterproof MPPT Voltage Boosting Solar Controller for Lead Acid Batteries with Aptiv Connectors

1: Panel ratings have increased since we designed the GVB-8-WP. Although we don't believe in changing specifications without a corresponding engineering change, based on both our customers' experiences over the years as well as the headroom we designed into the GVB-8-WP, we feel comfortable recommending the GVB-8-WP for panels with Imp up to 9 A.
2: Panel Isc. Max input power and maximum input voltage requirements must also be respected.
3: Max current that the controller could draw from an unlimited source. This specification is not intended for determining PV input.
4: Max ambient temperature for full operating power.
5: If the battery voltage drops below this point, the controller will attempt to run an absorption cycle. Otherwise, it will charge to the float voltage.
