Chargers
The primary function of the inverter in your solar power system is to produce 220~240V AC power from a 12V DC battery bank. More sophisticated inverters will come with the option for a built-in DC charger for your 12V battery system when you are plugged into shore power or running from your on board generator, allowing your trailer or RV to run off-grid. This feature serves to replace your existing on-board converter with superior battery charging set-points. Other RV solar inverter and charger kit systems may have an option for a pass-through AC function, or automatic transfer, that enables shore power (or a generator) to bypass the inverter when you’re “plugged in.” The most advanced inverters have a hybrid function that enables current to be drawn from shore power and a battery bank at the same time. This is a great feature running large appliances like air conditioners from a low current shore power source. Of course, the price point changes with the addition of these options.
