Installation and Operation Manual IMPORTANT SAFETY INSTRUCTIONS 1. Refer installation and servicing to qualified service personnel. High voltage is present inside unit. Incorrect installation or use may result in risk of electric shock or fire. No user serviceable parts in this unit. 2. -
Page 4: Product Description
A user friendly digital display is also available to monitor PV charge performance. The display may be provided in the Solar Boost 3048 controller, as a remote panel, or both. The remote panel cable may be up to 300ft/91.4m in length. -
Page 5: Current Boost
Installation and Operation Manual Once installed and configured, Solar Boost 3048 charge control and MPPT operations are fully automatic. Charge turns on whenever the PV array is capable of producing sufficient power. When PV charge is on the Charge Status LED will indicate the present charge mode, and when PV power production is relatively high, it will show approximate battery state of charge. -
Page 6: Charge Status Indicator
Bulk Charge During the bulk charge stage, the charge status LED will be on continuously. Solar Boost 3048 delivers as much charge current as possible during bulk to rapidly recharge the battery. In the bulk stage, the battery is typically at a low state of charge of less than 70% full. -
Page 7: Float Charge
TWO STAGE CHARGE CONTROL Certain battery types or system configurations may require two stage charge control. Solar Boost 3048 can be configured for a two stage bulk-acceptance or bulk-float charging process to accommodate these batteries or systems. -
Page 8: Optional Temperature Compensation
When conditions are such that sufficient PV voltage and current are not available to produce an increase in output current, Solar Boost 3048 will operate as a high performance series pass PWM controller. Current boost performance can be easily monitored using the digital display. Whenever output charge current is greater than solar panel current, current boost is functioning. -
Page 9: How Mppt Works
25°C, representative boost performance under a variety of operating conditions is shown in Table 2. Your current boost performance will vary due to a variety of factors. What you can be sure of is that Solar Boost 3048 will automatically deliver the highest charge current possible for a given installation and operating conditions. -
Page 10: Temperature And Output Power
Our interpretation of the spirit of the NEC is that Solar Boost 3048 connected to 24 amps of short circuit PV current, and branch circuit protection of 40 amps is compliant with the spirit of NEC requirements. This is because the system is rated for and electronically limited to 30 amps of output current. -

In this mode input current should be limited to 12 amps. Charge Mode Solar Boost 3048 can be configured for two stage or three stage charging. Typically three stage charge is used, but certain battery types or system configurations may benefit from two stage charge. When configured for two stage charge, equalization still operates as described. -

5 amps of charge current which is being provided by Solar Boost 3048. If a 10 amp load is then placed on the battery, Solar Boost 3048 increases output current to hold the battery at the desired acceptance voltage. -

For temperature compensation to operate, the SensorLug battery temperature sensor must be installed and the desired temperature compensation curve must be enabled. Solar Boost 3048 will not provide output current if temperature compensation is enabled with the SensorLug connection open (not installed), or if the SensorLug is shorted or installed reverse polarity. -
Page 15: Solar Boost 3048 Installation
SOLAR BOOST 3048 INSTALLATION The Solar Boost 3048 controller should be mounted to a vertical surface with the heatsink fins oriented vertically to promote convection cooling. If not mounted vertically, Solar Boost 3048 may reduce average output power to prevent damage due to over temperature. -
Page 16: Battery And Pv Wiring
The lengths shown are one way for the wire pair between the PV array and battery, with Solar Boost 3048 placed somewhere in the middle. Typically the Solar Boost 3048 is installed in a power room near the batteries, and the majority of the wiring travels from the Solar Boost 3048 to the PV array. -
Page 17: Optional External Current Shunt
If used, the external shunt should be installed in the battery negative cable and connected to Solar Boost 3048 as shown in Figure 3 so that it measures net battery current only. -

RV Power Products - Solar Boost 3048 The power source must be able to operate open circuit. This is because Solar Boost 3048 uses series pass type control to lower output power when necessary. The input may go fully open circuit when the battery is fully charged. Periodic open circuit operation is also used by the MPPT system. - Page 19 Installation and Operation Manual SYMPTOM PROBABLE CAUSE ITEMS TO EXAMINE OR CORRECT Charge current is Battery is highly charged Normal operation, system will be in Acceptance or Float and lower than expected, current is reduced to control battery voltage. PV current may be low as well Worn out PV modules Replace, or use as is.
