Specs:
This controller prevents harmful over charging by adjusting the power generated by a solar panel before it reaches your RV batteries. It uses maximum power point tracking technology to compare solar output to battery voltage and converts that output to an optimal amperage. Typically, this type of technology is a good fit for larger systems with higher voltages.
Automatic Multistage Charging System
Using a multistage charging system, the controller automatically switches voltages while the battery bank charges. This accelerates the charge, but also helps extend battery life by adjusting the voltage during the different modes. The controller is compatible with multiple battery types and includes preset charging profiles for sealed/gel, AGM, and LiFeP04 (lithium) batteries.
Charging Modes
1. Bulk: This mode charges at the full rated load for a quicker recharge time. As the name suggests, this is where the bulk of the charging happens. It typically charges the battery to at least 80% capacity.
2. Absorption: This mode provides controlled voltage to ensure a full charge. Once the battery reaches between 80% to 90% capacity, the absorption state will kick in and start charging at a regulated voltage. In each charging profile, this mode is set to last for 30 minutes after the bulk charge is completed.
3. Float: Once the battery reaches full charge, this mode maintains a lower voltage to compensate for self-discharge. This reduces battery stress and minimizes gassing and water loss.
Practical, Convenient Features
This solar controller comes with a sensor that enables temperature compensated charging. As the controller experiences changes in temperature, the sensor compensates for those changes by adjusting the voltage during charging to help extend the life of your batteries. This protects from overcharging in hot temperatures and under charging in cold temperatures.
The controller also includes several built-in safety features to help protect your equipment. The charging process will shut down if the controller starts to overheat and when an overcurrent is detected. Also, if the battery or solar panel is wired incorrectly, it activates a reverse polarity alarm.

Review from a similar Net-Zero in Solar Charge Controllers
I bought this charger because it was supposed to charge lithium ion and lead acid batteries. Though it is technically true, this charger unfortunately is unable to fully charge such batteries, particularly lithium ion. The charge voltage never exceeded 13.3 volts, unless the battery was very depleted. To fully charge such batteries, voltage must approach over 14 volts, preferably 14.4 (depending on specific battery requirements). I contacted the manufacturer who took weeks to reply confirming the above.

What is the measure of a excellent converter? That you don't even know it is there. One year after installation, that is surely the case with this unit. I don't hear it, it is never hot, it is keeping the battery in great condition and it takes up very little space compared with what it replaced.
