Linear Current Boosters
We like to use one piece of modern technology on PV-direct systems that isn’t often found on battery-powered systems. A linear current booster, or LCB for short, is a solid-state marvel that will help get a PV-direct pump running earlier in the morning, keep it running later in the evening, and sometimes make running a possibility on hazy or cloudy days. An LCB will convert excess PV voltage into extra amperage when the modules aren’t producing quite enough current for the pump. The pump will run more slowly than if it had full power, but if a positive-displacement pump runs at all, it delivers water. LCBs will boost water delivery in most PV-direct systems by 20% or more, and we usually recommend a properly sized one with every system.
