The 2024 SolarFlex 1320i-L package combines 1,320 watts of roof-mounted solar, 540Ah of lithium battery capacity, and Victron inverter/charger technology to support camping without hookups. Available on 2024 Montana models, it provides power for onboard systems, outlets, and supported air-conditioning operation. Actual runtime depends on battery charge, sunlight, appliance demand, and system limits.
Also called SolarFlex Outlast Extreme 1320i-L, the 2024 package includes:
The solar panels collect energy, the charge controllers manage solar charging, and the batteries store energy for later use. The inverter converts battery power into AC power for connected equipment, while the monitoring components help owners track system operation.
SolarFlex 1320i-L supports essential 12-volt systems and inverter-connected AC loads, giving owners more flexibility when camping away from shore power.
The package also supports air-conditioning operation within the installed system’s limits. Soft starts reduce air-conditioner startup demand, but air conditioning still uses substantial energy.
Keep these distinctions in mind:
Use the GX Touch display and battery monitor to compare consumption with charging and adjust appliance use accordingly.
The Victron inverter/charger includes PowerAssist, which can supplement a limited shore-power source with battery energy when properly configured.
This helps manage demand that temporarily exceeds the selected AC input limit. It does not turn a household outlet into an unlimited 30-amp supply. Assistance depends on available battery energy and the inverter’s operating limits.
Solar and shore power can both contribute to charging when conditions and settings permit. When demand requires battery assistance, however, the batteries may discharge even while the RV remains plugged in.
Confirm the correct input-current limit and connection requirements before using a reduced-capacity power source.
For the 2024 model year, SolarFlex 1320i-L was offered exclusively on Montana models. Confirm the installed package on your individual RV rather than assuming every Montana has the same equipment.
Other packages in the 2024 SolarFlex lineup included:
Compatible Zamp portable solar panels can connect through the prewired sidewall port to supplement solar charging.
Confirm panel compatibility and charging requirements before connecting equipment. Additional collection can help replenish batteries, but charging performance remains dependent on sunlight and system capacity.
The published expansion option includes additional Dragonfly Energy® heated lithium-ion batteries, KRV part number 653851, with a parallel cable kit through an authorized Keystone dealer.
Have the dealer confirm battery compatibility, installation requirements, and part availability before expanding the bank. More battery capacity can increase stored energy, but it does not increase the inverter’s output rating.
The following specifications describe the panels and charge controllers listed for the 2024 package. Check installed component labels before ordering replacements.
These panel ratings do not establish the voltage or temperature limits of the complete RV solar system.
Review the 2024 SolarFlex 1320i-L Quick Start Guide before operating or expanding your system.
