Hybrid Inverters – From Battery to Solar

If you are looking for a long-term modular approach towards energy security, plus savings, for a house, office or holiday cottage, then starting with a battery backup system that is fully expandable to solar PV may be the smart way to go. Being on the approved list of the CoCT and other municipalities will be an important consideration when choosing the equipment.

One of AWPower’s favourite choices are the Victron Multiplus-II 3kVA and 5kVA hybrid inverters because of its almost limitless expansion capability as it can be paralleled, i.e. 3 + 3 + 3 + 3 = 12kVA and more. Up to 54kVA output can be achieved with the 3kVA hybrid with approval by CoCT or CityPower, making it possible to support an example load of up to 720 PC laptops @ 60W each. You can start with 4.8kWh AGM/Gel or lithium batteries which can also be expanded as required.

When your budget allows, solar PV modules may be added without having to replace any components. A major benefit in opting for a hybrid inverter is the ability to switch between battery and/or the grid as a source, and to supplement energy from solar PV, without requiring any intervention from the user. During load shedding your essentials will continue to run off battery/solar.
Internet access to the system will provide performance statistics and allow for remote support.
We have selected 3 options (single-phase) for you below:

Option 1 – 3kVA/100Ah 48v with AGM battery backup

R39 378 (Excl. VAT)

Excluding: Battery box and major rewiring of existing DB, delivery cost to Gauteng region.

Backup Capacity: 4,8kWh @ 100% Depth of Discharge (DoD), estimated 3-hour backup time @ 50% DoD with a load of 800W.

Typical load 800W: TV (100W) +WiFi Router (15W) +Desktop PC (200W) + 8 Laptops (8 x 60W)


Option 2 – 3kVA/100Ah 48v with Lithium battery backup
R59,995 (Excl. VAT)

Including: As above with 2 x US2000 Pylontech lithium batteries, Battery Cabinet & Wiring Harness. Delivery & electrical Installation allowance of R6,704.

Excluding: Major rewiring of existing DB, delivery cost to Gauteng region.

Backup Capacity: 4,8kWh @ 100% Depth of Discharge (DoD), estimated 4-hour Backup time @ 89% DoD with a load of 1000W.

Typical load 1000W: WiFi Router (15W) +Desktop PC (2 x 200W) + 9 Laptops (9 x 60W)


Option 3 – 3kVA 48v (4.8kWh) Lithium with 3.1kWp Solar PV
R99 894 (Excl. VAT)

Or instalment of R2,324 (Excl. VAT) over 60 months for approved businesses.

Including: Option 2 + Solar Charge Controller + Energy Meter plus 9 x 340Wp = 3.1kWp PV modules. Delivery, electrical & PV Installation allowance of R7,894.

Excluding: Major rewiring of existing DB, delivery cost to Gauteng region.

Backup Capacity when the sun is down: Lithium 4,8kWh @ 100% Depth of Discharge (DoD), estimated 11 hours Backup time @ 89% DoD with a baseload of 400W average (during the night).

Typical load (non-essentials circuit): Geyser (on timer) with element reduced to 1.5W, stove, limit number of 15A wall plugs.

Typical load (essentials circuit): Wi-Fi, alarm, lights, 15A sockets feeding essentials such as TV, PC/Laptops, fridge etc. During load shedding the inverter will drop the non-essentials AC circuit and feed only the essentials AC circuit.

Typical night baseloads of 400W will maintain outside LED lights, Wi-Fi Router and alarm system and a few hours of TV.
