System types

System types Off-grid No grid available. Use battery as a buffer, buffering solar energy and/or energy coming from a genset. Bad-grid -> Intentional Islanding Very unreliable and unstable grid. Use a battery and PV, run in inverter mode when possible and only fall back to the grid when necessary. (ignore AC) Unreliable grid / Marine / Automotive: backup Grid frequently fails: a battery is used to power loads when mains is not available. Energy storage Use a battery to store excess solar power (day), to later use it when there is not enough solar power available to power the loads (evening and night). Grid is stable, and 99.99% available

ESS Assistant - Perfect for Energy Storage Systems

Base

Standard AC-coupled PV

Add the Energy Storage & Meter

Add critical loads

AC-Coupled PV on output

DC-Coupled PV

AC Coupled PV on input

All (or a combination) is also possible

New! ESS Assistant without meter

Pure Energy Storage - no PV

BatteryLife “There is no point in discharging a battery today / tonight, when you already know that it will not be recharged tomorrow.” Longer battery life for lead & passive balanced Lithium Be prepared for a mains outage Mandatory for Victron 12.8V lithium batteries, because they have passive balancing no BatteryLife -> no warranty!

Perfect Energy Storage System Easy configuration in the CCGX Compatible with many battery brands DC-Coupled and/or AC-Coupled PV Enable/disable feed-in Zero feed-in for Fronius PV Inv.

ESS Details

What about the Hubs? Hub-1: deprecated except for policy 3: Invert priority Hub-2: deprecated except for policy 2: Invert priority Hub-4: deprecated entirely What does deprecated mean? It means no support. In case of problems, first update to ESS, and then contact us again in case of trouble.

No feed-in systems Use an MPPT, do not use a PV Inverter Still want to use a PV Inverter? Then at least take a Fronius. (and use Zero Feed-in) Remember: to prevent feed-in for a PV Inverter, you need to sabotage it. Leads to flickering, overloads, and more problems.
