2ANPB-RIV4835PCS 48V 3500W Solar Inverter Charger

Product Information

Battery Charge Mode (Parameter 06)

The battery charge mode determines the source of charging for
the battery. The available options are:

Default: Solar panels and the grid charge the battery
simultaneously, with solar energy being the first charge source.
The grid becomes the primary charge source when solar energy is
insufficient and stops charging the battery when solar energy is
sufficient.
Solar Only: Solar energy is the only charge source, even if the
grid is available.
Solar First: The battery is first charged by the solar panels.
The grid charges the battery only when solar energy is
unavailable.
Grid First: The battery is first charged by the grid. The solar
panels charge the battery only when the grid is unavailable.

Battery Type (Parameter 08)

The battery type setting determines the charging voltage for the
battery. The available options are:

Default (Sealed lead-acid/AGM): Constant charging voltage –
58.4V, float charging voltage – 55.2V.
Flooded lead-acid: Constant charging voltage – 58.4V, float
charging voltage – 55.2V.
Gel lead-acid: Constant charging voltage – 56.8V, float
charging voltage – 55.2V.
Lithium iron phosphate: Corresponding to 14 strings, 15
strings, and 16 strings. Default constant charging voltages are
50.4V, 54V, and 57.6V respectively.
Lithium-ion: Corresponding to 13 strings and 14 strings.
Default constant charging voltages are 53.2V and 57.2V
respectively.
User-defined battery type: Allows customization of all battery
parameters. Refer to the Renogy 48V 3500W Pure Sine Wave Solar
Inverter Charger user manual for detailed instructions.

Note: Setting the wrong battery type may cause damage to the
inverter charger and will not be covered under warranty.

N-G Bonding (Parameter 41)

The N-G Bonding feature ensures that the neutral contact of the
RV is always grounded, preventing electrical shock caused by
contact between the neutral contacts of the RV and external AC
power sources. The available options are:

Enabled (default): N-G Bonding is enabled.
Disabled: N-G Bonding is disabled.

Overcurrent Protection

The inverter charger is equipped with an input breaker that
automatically cuts off the AC input when the current exceeds 40A.
This helps protect the inverter charger from damage. Ensure that
the AC input current does not exceed 40A.

System Upgrade

The inverter charger firmware can be upgraded using the USB
Debugging Port. Store the firmware upgrade file on a USB drive and
connect it to the USB Debugging Port of the inverter charger. Enter
Parameter 40 to complete the upgrade. Refer to
renogy.com/contact-us for detailed instructions.

Important Safety Instructions
General
z Wear proper protective equipment and use insulated tools during installation and operation. Do not wear jewelry or other metal objects when working on or around the inverter charger.
z Keep the inverter charger out of the reach of children. z Do not dispose of the inverter charger as household waste. Comply with local, state, and federal laws and regulations
and use recycling channels as required. z In case of fire, put out the fire with a FM-200 or CO2 fire extinguisher. z If the inverter charger is installed improperly on a boat, it may cause damage to components of the boat. Have the
inverter charger by a qualified electrician. z Do not expose the inverter charger to flammable or harsh chemicals or vapors. z Clean the inverter charger regularly to ensure the cooling fans are not blocked. z It is recommended that all cables should not exceed 10 meters because excessively long cables result in a voltage drop. z The cable specifications listed in the quick guide account for critical, less than 3% voltage drop and may not account for
all configurations.
Inverter Charger Safety
z There are no serviceable parts in the inverter charger. Do not open, dismantle, repair, tamper with, or modify the inverter charger.
z Confirm the polarities of the devices before connection. A reverse polarity contact can result in damage to the inverter charger and other connected devices, thus voiding the warranty.
z Ensure the inverter charger is firmly grounded to a building, vehicle, or earth grounded. Keep the inverter away from EMI receptors such as TVs, radios, and other audio/visual electronics to prevent damage / interference to the equipment.
z The inverter charger generates heat when working. To prevent burns, touch the LCD only when the inverter charger is working.
z After the Inverter charger is powered off, the internal high voltage in the inverter charger will last for about 5 minute. z Do not parallel the inverter charger with other AC input sources to avoid damage.
Battery Safety
z Risk of electrical shock! Ensure the connected battery is turned off before connecting it to the inverter charger. z Do not touch the exposed electrolyte or powder if the battery is damaged. z Risk of explosion! Never install the inverter charger in a sealed enclosure with flooded batteries! Do not install the
inverter charger in a confined area where battery gases can accumulate. z Prior to installing the inverter charger, ensure all battery groups are installed properly. z The inverter charger should be as close to the battery as possible to avoid voltage drop due to long cables. z Ensure the battery voltage is within the normal range of 40V to 60V. If the battery voltage is lower than 40V, the inverter
charger fails to detect the battery. If the battery voltage is higher than 60V, the inverter charger is damaged. z If the battery voltage is lower than 44V, the inverter charger cannot be powered on.

Solar Panel Safety
z Do not use the solar panel(s) if there is any damage. z Prior to connecting the inverter charger to the solar panel(s), shade the solar panel(s).
Grid or AC Generator Safety
z Risk of electrical shock! Ensure the grid or the AC generator is turned off before connecting them to the inverter charger. z The inverter charger can only be connected to 120V single-phase power systems through the AC Input Port. Otherwise,
the inverter charger will be damaged.
