19) Low Battery Time On: Sets the amount of time the B801 will hold the REbus™ DC Microgrid to 340V
and attempt to start “Bulk” cha rging the batteries. See Section 7.5 - 7.5.1 Low Battery Voltage for more
detailed information.
20) Relay Turn On Voltage: This is the battery voltage at which the relay will turn “ ON ”. This means that
the normally closed contact will open, and the normally open contact will close. In the “OFF” state t he
normally closed contacts will be closed and the normally open contacts will be open.
21) Relay Voltage Hysteresis: After the relay is “ ON ” it will stay in that state until the voltage drops
below the “Relay Turn On Voltage” minus this setpoint. This setpoint is the voltage difference between
“Relay Turn On Voltage” and what would be the “Relay Turn Off Voltage”. For example if you set your
“Relay Voltage Hysteresis” to be 2V and your “Relay Turn On Voltage” is set to 50V then the relay will
turn on at 50V and off at 48V.
22) Relay Time Hysteresis: The minimum amount of time that the relay must remain OFF after being
ON. Regardless of what the battery voltage does after it dropped below the threshold (Relay Turn Off
Voltage minus Relay Voltage Hysteresis) the relay will stay OFF for this specified amount of time. This
protects whatever is connected to the relay from frequent switching ON and OFF.
8 Internet Compatibility
The Wi-Fi features of the B801 are entirely optional and can be connected/disconnected in the settings
menu, accessible from the LCD screen. Note that in order to receive firmware upgrades and to use the
Pika REview™ online monitoring system (See section 8.4 Pika account and the REview™ online
monitoring system) you must be connected to the internet.
At Pika Energy, we believe that people make better energy decisions when their energy information is
depicted in an easy to understand and intuitive format. For this reason, the B801 is designed to display
its vast amount of energy information on a Pika-supported website called
REview™ for visualization and
analysis. The website offers the user several graphical options for viewing his or her energy production.
These include energy (kWh) plotted monthly and daily for 30 years, hourly for the previous year and by
minute for the past 24 hours.
The website also provides status reports, event logging and graphics of the energy production for each
component of the system. After connecting your B801 to the internet, log on to
http://profiles.pika-
energy.com/ to make an account, register your hardware and setup your REview page.
8.1 Wi-Fi Antenna
The Pika B801 is shipped standard with a Wi-Fi antenna that should offer good performance for most
installations within 150 feet of a wireless router. For installations where the charge controller is located
at a large distance from the Wi-Fi router, the signal strength may not be adequate. Signal strength can
be monitored on the Wi-Fi Page of the LCD Display (see Section 6.3.3). In this case, a higher-gain
antenna can be purchased to improve the connection to the Wi-Fi router. Most electronic component
suppliers offer compatible antennas with SMA connectors. Most 802.11 antennas with SMA connectors
