• Do not install in locations where water can enter the
controller.
• Loose power connections and /or corroded wires
may result in resistive connections that melt wire
insulation, burn surrounding materials, or even cause
fire. Ensure tight connections and use cable clamps to
secure cables and prevent them from swaying in mobile
applications.
• Preset charging profiles are generally designed for
lead acid batteries. Custom settings can be used for
varied charging requirements (see sections 3.2 and 4.7
for details). Note that some battery types may not be
compatible.
• The EcoBoost MPPT battery connection may be wired
to one battery, or a bank of batteries. The following
instructions refer to a singular battery, but it is implied
that the battery connection can be made to either one
battery or a group of batteries in a battery bank.
• The EcoBoost MPPT uses self-tapping fasteners,
an anodized aluminum heat sink, and conformal
coating to protect it from harsh conditions. However,
for acceptable service life, extreme temperatures and
marine environments should be avoided.
• The EcoBoost MPPT prevents reverse current leakage at
night, so a blocking diode is not required in the system.
• The EcoBoost MPPT is designed to regulate ONLY solar
(photovoltaic) power. Connection to any other type of
power source e.g. wind turbine or generator may void
the warranty. However, other power sources can be
connected directly to the battery.
• The maximum power terminal wire size is #6 AWG /
16 mm
2
(solid/multi-strand) or #8 AWG / 10 mm
2
(fine
strand). Use a flathead insulated screwdriver, and
torque tightly up to 3.95 Nm.
• Stranded wires to be connected to the EcoBoost MPPT
terminals should be prepared first with e.g. clamped
copper heads, etc. to avoid the possibility of one
conductor free out of the connection screw, and
possible contact with the metal enclosure.
WARNING:
Solar and battery fuses or DC breakers
are required in the system. These protection devices
are external to the EcoBoost MPPT controller, and must be a
maximum of 25 amps for the EB-20/M, 35 amps for the EB-
30/M, and 50 amps for the EB-40/M.
WARNING:
Breakers and fuses may require lower
ratings than referenced above, so as not to exceed
any specific wire ampacity.
WARNING:
Minimum over-current protection
device interrupt ratings must be 2000A for 12V
systems, and 4000A for 24V systems.
3.2 Configuration
The DIP switch block shown in Figure 3.1 below is used to
set the operating parameters for the EcoBoost MPPT.
