Just bought a used class B with RCV-30-moot (82890) doesn’t seem to be charging.led by #1 and the led by middle battery icon. The sun icon isn’t lit is this condition normal . The battery is at 93% (from shore power)

Congratulations on purchasing your Go Power! GP-RVC-30-MPPT Solar Controller! Record the unit’s model and serial number below. It is much easier and quicker to record this information now at the pre-installation stage. Model Number: Serial Number: Date of Install: Battery Bank Information:...
1. SAFETY Important safety information is contained throughout this manual that should be carefully observed and followed. This information is presented using the following format: Warning / Caution: Result Description of condition leading to result SYMBOL The information is categorized in two ways: Warning: Bodily harm could occur if instructions are not explicitly followed.
2. INTRODUCTION 2.1 OVERVIEW The 30A RV-C MPPT solar controller is an advanced dual bank controller with RV-C communication for smart RV sys- tems. As an MPPT Solar controller it continuously monitors the solar panel’s generating power and tracks the maximum power point, enabling the system to charge the battery with maximum power all the time.

4. MAXIMUM POWER POINT TECHNOLOGY Maximum Power Point Tracking (MPPT) is an advanced charging technology that more efficiently harvests power from solar panels in all conditions. It does this by continuously tracking the I-V curve of the solar array and modifying operating conditions to maximize output power.

MAXIMUM POWER POINT TECHNOLOGY The graph below shows how the IV curve of a solar panel changes with varying temperatures. In partially shaded conditions there can also be multiple peaks in the P-V curve that can confuse an MPPT algorithm. Shown in the diagram below is a series string of solar panels.
5. CHARGING STAGES Maximum power point tracking is used to charge the batteries with the highest current possible, but this is only part of the equation. A battery cannot be charged at maximum power all the time for safety reasons, so multiple stages are used. These stages include: bulk, absorption, float and, for some types of batteries, equalization as indicated below.

CHARGING STAGES STAGE 4: EQUALIZE Warning: Risk of explosion! Equalizing vented lead-acid battery may generate explosive gases. So, the battery compartment must be well ventilated. Caution: Damage of device! Equalization can increase the battery voltage to levels that may damage sensitive DC loads. It is necessary to verify that the allowable input voltage of all system loads is greater than the equalizing charge set value.
6. DUAL BATTERY CHARGING The GP-RVC-30-MPPT has two battery outputs: BAT1 and BAT2. The solar controller will prioritize BAT1 at all times to ensure it is always charged as much as possible. After BAT1 has completed absorption charging excess power will be used to charge BAT2.

10. INSTALLATION 10.1 TOOLS AND MATERIALS NEEDED • Screwdriver • Drill • Multimeter 10.2 INSTALLATION AND WIRING STEP 1: CHOOSE AN INSTALLATION LOCATION The following things should be considered when choosing an installation location for GP-RVC-30-MPPT controllers. • The controller should be installed indoors where it is safe from water or condensation •...

Wiring and installation must comply with national and local electrical code requirements. The wire from the solar array most commonly enters the RV through the fridge vent on the roof or by using the Go Power! Cable Entry Plate (sold separately) that allows installers to run wires through any part of the roof. PV connections should connect directly to the controller.
11. RV-C INSTANCE NUMBER 11.1 RV-C INSTANCE NUMBER IDENTIFICATION The RV-C instance of an individual controller can be identified by the 5 LEDs on the controller shown below. 11.1 CHANGING THE RV-C INSTANCE NUMBER The instance of the solar controller on the RV-C network can be configured using the SET button and LEDs. Up to 5 unique instances are supported.
