Solar

3200 Watts at max zenith. This is about 250A full charge capability
Panels are wired in series for an output voltage of 100v max
Each solar pair goes to a Victron Solar MPPT charge controller
Typical output float voltage of ~13.5v
Each MPPT controller has an 80A circuit breaker
The 4 MPPT’s are wired to an ANL 300A fuse connected to the batteries

Batteries

10 300 hr (3000Ahrs) 12-14v Relion LiFePObatteries, wired in parallel
Each battery is protected with a 150A fuse located on the positive terminal of the battery
Each battery has internal overcurrent, overvoltage, and under voltage protection
The battery bank supplies the positive bus bars
The vessel 12v supply is connected to the positive bus bar via the existing fuse

Quatro Inverter/Charger:

5000W Victron 230v 50Hz
Automatic switchover from AC input to Inverter mode
Automatic charge mode when AC input available
Charge capability up to 180 Amps
Works with shore power or generator
Provides power to the air conditioners and water maker
normal float voltage of ~13.5v, once every 7 days it will take the batteries up to 14.2v for 1 hour.
Connected to the batteries via an On/Off switch and a 750A ANL fuse

DCDC Converters:

A DCDC converter on both starter batteries
Provides up to 50A each charging the LiFePO4 when the engines are running, or plugged into shore power, or running on the generator
Setup to deliver a fixed 13.5v to the batteries

Battery Voltage monitor:

Victron BMV-712 500A current and voltage monitor

Operation:

All systems are designed to be fully automatic. When plugged in or running on the generator, AC power is passed through Quattro 5000 to the Air conditioners and watermaker. Charging also occurs if needed. All the charge sources, solar, DCDC’s, and the Quatro are programmed for LiFePO4 batteries.

Expected Power consumption:

While using the batteries with no charge source ( night and no generator, engines running, or plugged in) we measured 250A or 3200watts with all the Air Conditioners on. With a battery bank of 3000 hrs, expect between 12 and 24 hours, depending on state of charge at the start, outdoor temperatures, thermostat settings, and how many AC’s are on.

During the day with full, solar will augment the power consumption and longer operation can be expected. Even if cloudy, there will still be some power supplied.

Charging Capability:

250A peak for solar
180A from the Quatro 5000
80A from the Quatro 3000
100A from the DCDC

Total charging current is 610A. This would only occur at high noon and the batteries are at 12v. Typical operation would be to see 250A charge current.

When to start the generator or plug in:

The system will shut off the inverter when the battery is below 11.5v. The batteries will shut off around 10v to prevent internal damage. It is advised is to start the generator at or below 12v. 12v is approximately 20% power remaining, requiring an 80% refill. If at night expect to run the generator for 3000Ahr / (180+80+100) * 0.8 = 6 hours to get to full charge.

When running the vessel offshore at night, DCDC’s will provide up to 100A of charging from the engine alternators. This is not enough to cover the load of all air conditioners, but will supplement the power, extending the air conditioners operational run time.

Relion Battery internal protection:

The Relion batteries are designed to protect themselves from abuse. There is an internal protection circuit that will disconnect the battery if under voltage, over voltage or over current. If this occurs, identify the cause (most likely the voltage was too low). Disconnect the negative of the battery, verify there is a charge source, measures >13v, and reconnect the battery. The internal switch will turn back on.
