Victron MultiPlus 5kva Inverter Charger - 4.8kwh Lithium Battery - 3.2Kw Solar. OG16

An off-grid power system is for those living or operating off-grid with no access to mains power. A Victron off-grid system is designed to supplement a generator to provide power more sustainably, store energy from the sun for later use and to offset fuel costs.

Key Components in the System

Solar Panels:

• These capture sunlight and convert it into electricity.
• Solar energy powers your home and charges the batteries during the day.

Battery Bank:

• Stores energy generated by the solar panels.
• Supplies power at night or when solar production is low (e.g., cloudy days).

Victron Inverter/Charger:

• Converts DC power from the batteries or solar panels into AC power used by household appliances.
• Manages the charging of batteries from solar or the generator.

Generator:

• A backup power source that kicks in when the solar panels can’t produce enough energy, and the batteries are depleted.
• Provides additional power during prolonged cloudy weather, winter, or high energy demand.

1. Victron Smart Controller:

• Oversees the entire system, ensuring power flows efficiently between solar, batteries, and the generator.

How the System Works

Normal Operation:

• During sunny days, solar panels generate power for immediate use and charge the batteries.
• Excess solar energy is stored in the batteries for use during the night or when the sun isn’t shining.

When Solar Isn’t Enough:

• On cloudy days or during winter, when solar production is low, the system uses stored battery power.

1. Backup Generator:

• If the batteries run low, the generator automatically starts (if enabled) to provide power and recharge the batteries.
• Once the batteries are sufficiently charged, the generator turns off, and the system goes back to using solar.

Why a Generator is a Good Backup

Reliable Energy During Extended Cloudy Periods:

• In regions like the UK, where sunlight hours can be very low in winter, a generator ensures you’re not left without power.

Covers Peak Loads:

• If your energy demand suddenly spikes (e.g., using heavy appliances), the generator can provide the extra power without overloading the system.

Battery Longevity:

• Running batteries down to very low levels frequently can shorten their lifespan. A generator prevents this by recharging the batteries when needed.

Peace of Mind:

• It ensures you always have power, even during unforeseen circumstances like prolonged bad weather or high energy demand.

1. Scalability:

• If you add more devices or appliances in the future, the generator can compensate for increased energy needs until you upgrade your solar or battery system.

The capacity of the Victron inverters (3kVA, 5kVA, 8kVA, 10kVA) determines the total load they can handle at a given time. Here’s a breakdown of the typical household or power requirements they might power, depending on the size of the inverter:

3kVA Inverter

Typical Applications:

• Suitable for small households or basic setups.
• Can power essential appliances:

Lights (10–15 LED lights)

Ceiling fans (3–5)

TV (1–2 units)

Refrigerator (1 medium-sized unit)

Laptop/PC (1–2 units)

• Load Limitation: Cannot support high-load appliances like electric stoves, air conditioners, or water heaters simultaneously.
• Total Load Capacity:
• ~2400W (assuming an 80% efficiency and typical 220-240V supply).

5kVA Inverter

Typical Applications:

• Suitable for medium-sized households.
• Can power a mix of essentials and a few high-consumption devices:

Lights and fans (as above)

TV, refrigerator, and a single air conditioner or washing machine.

Kitchen appliances like a microwave or kettle (if not used simultaneously with other high-power devices).

• Load Limitation: May struggle with simultaneous use of multiple heavy appliances.
• Total Load Capacity:
• ~4000W.

8kVA Inverter

Typical Applications:

• Ideal for large households or small commercial setups.
• Can power:

Multiple air conditioners (up to 2–3 units).

Refrigerator, lights, and fans.

Washing machine, microwave, and other kitchen appliances.

Entertainment systems and computers.

• Load Limitation: Can handle most residential needs but not all heavy appliances simultaneously.
• Total Load Capacity:
• ~6400W.

10kVA Inverter

Typical Applications:

• Suitable for large homes or offices with high power demands.
• Can power almost all household appliances simultaneously:

Multiple air conditioners (3–5 units).

Refrigerators, freezers, and kitchen appliances.

Electric stoves, geysers, or water heaters.

Entertainment systems and home automation setups.

• Load Limitation: Limited primarily by the battery bank or grid support.
• Total Load Capacity:
• ~8000W.

Board Build 5kVa Multiplus with 100Amp Transfer Switch plus 70 Amp Battery Charger with 8 large solar panels 400w (3.2kw) including Cerbo GX Monitoring + Touch Screen + Lynx Distributor+ Slave Consumer Unit + Isolation Switches + Cabling + 3 pin Socket  + Trunking Ect.

An Inverter/Charger with device networking built-in, the MultiPlus-II GX communicates with a solar charger, batteries, and other devices to control a grid-connected, off-grid, or remote power installation. Capable of parallel operation for increased power output, or battery charge-rates, the MultiPlus-II GX can also be configured for three-phase supply. A host of advanced features - such as uninterrupted power supply, setting load limits, and supplementing limited grid-power availability with battery power - can all be controlled straight from your phone or smart device. Remote monitoring is also possible.

The MultiPlus-II combines the functions of the MultiPlus and the MultiGrid.
It has all the features of the MultiPlus, plus an external current transformer option to implement PowerControl and PowerAssist and to optimize self-consumption with external current sensing (max. 32A).  It also has all the features of the MultiGrid with built-in anti-islanding and an increasingly long list of country approvals.

PowerAssist

The MultiPlus-II will prevent overload of a limited AC source, such as a generator or shore power connection. First, battery charging will automatically be reduced when otherwise an overload would occur. The second level will boost the output of a generator or shore side supply with power taken from the battery.

ESS: Energy Storage Systems

The MultiPlus-II is the key component in a Victron ESS system, providing the flexibility to combine with MPPT Solar Chargers or Grid-tie PV Inverters. For examples and more detailed information see the Victron Energy ESS (Energy Storage System) manual.

Uninterrupted AC power (UPS function)

In the event of a grid failure, or when shore or generator power is disconnected, the inverter within the Multi is automatically activated and takes over the supply to the connected loads. This happens so fast (less than 20 milliseconds) that computers and other electronic equipment will continue to operate without disruption.

Remote Monitoring and Control

Monitor and control your Multi and system or systems' locally (LAN) or remotely via the internet from anywhere in the world, using the free VRM app and free VRM portal website. Access can be from a phone, tablet, laptop or PC for multiple operating systems. There is no end to the level of control, via the required Color Control GX or Venus GX, from adjusting your Multi to auto starting a back generator and more...
