8.0 Kw Victron Off Grid Solar System

This 8.0 Kw Victron Off Grid Solar System uses the tried & proven Victron 8.0 kW EasySolar Inverter Charger system, coupled with 48 x 265 w Canadian 60 cell PV module solar panels and 48 x FNB MTE25 S 1660 Solar Batteries, that offers higher cycle life and a lower discharge rate than cells in conventional applications.

Daily Averages.

On average, there will be 5kW-hours of power available from the solar array per day – based on 5 hrs of effective sunshine per day. More sunshine = more power. This Solar Electricity PV design reduces the amount of time the batteries will be low on charge. This will maximize the batteries life expectancy and provides far more reliable power.

Limited Sunshine or Overcast Days

On limited sunshine or overcast days, the battery reserve capacity will give the following power from full charge down to 50%:

• 8.0kW-hours for one day, or
• 4.0kW-hours per day for two days, or
• 2.0kW-hours per day for three days

Include a Petrol or Diesel Generator

The solar array can then recharge the battery bank from 50% in around 3 hours of effective sunshine, depending on any loads running on the system at the same time. A generator can be used to recharge the battery bank and run loads through the inverter at the same time too.

Monitoring

Detailed battery information is displayed on the BMV-702 battery monitor, and solar panel info is displayed on the MPPT control.

The Sealed GEL Deep Cycle Maintenance-free Batteries

The sealed GEL deep cycle maintenance-free batteries have an exceptional cycle life of around 1200 cycles to 50% discharge, which means the batteries could last around 9 years if they’re not discharged to more than 50% every three days at worst and kept insulated from temperature extremes.

Create an Off Grid power system

Create an Off Grid power system. Power will be supplied primarily from the solar panels & battery bank. If there is insufficient power, the inverter can make use of a petrol or diesel powered generator to recharge the batteries & run the household loads. The system can start the generator automatically providing the generator is compatible with two wire starting – some ATS systems are also compatible with two wire start.

Create a Grid-Hybrid system

Create a Grid-Hybrid system, where your Solar energy is used & stored as first priority. Power will be supplied primarily from the solar panels & battery bank. If there is insufficient power, the inverter supplements power using the Grid AC power supply automatically. This design principle uses your solar & stored energy first before using the mains grid power. This can be more feasible than the low grid feed-in tariff typically on offer. Victron’s Battery Safe feature retains a set amount of charge in the battery bank, utilising the mains to keep the battery operating in the optimal range. A generator can be used in place of grid power for charging the batteries and running loads in the event of a few cloudy days or some heavy power usage.

8.0 Kw Victron Off Grid Solar System does not feed back into the grid

Please note that this system will not feed energy back into the grid! Instead, all your solar energy harvest is used by your household with solar priority mode. The inverter can recharge the battery bank from the generator or mains power if there have not been enough sunny days.
