Extra start-up power
A unique feature of the SinusMax technology is very high start-up power. Conventional high
frequency technology does not offer such extreme performance. Phoenix Inverters, however, are
well suited to power up difficult loads such as computers and low power electric tools.

Experience the Excellence of Our State-of-the-Art 24V Inverter for All Your Power Needs. The 24V Victron Inverter 1200W Stands Out for Its Efficiency and Durability.

Solar energy is becoming the norm in Australia as we have crossed Germany by having 600 watts per capita and now stand at the highest per-capita solar capacity. The figures revealed the growing trend of using solar energy to power home appliances as Australia increased its solar capacity ten times from 2009 to 2011 and quadrupled for the 2011 and 2016 time periods. The increase in solar energy consumption has reduced the cost of solar equipment, and now we have affordable yet premium solar setups. The solar power setup comes in different variations, and you may choose whatever meets your requirements.

Solar energy systems comprise solar panels to catch sun rays and inverters to convert DC supply from panels to AC supply to provide for consumption. Inverters are the brain of any solar backup system. There are inverters in different capacities, like 12v, 24v, 48v, etc. The question is, what is the right and more suitable one. The 12v inverters are the most common ones that are in use, while the 24v inverter comes with some cost-saving approach and is efficient in various ways.

Further, the energy requirements will determine the asking voltage rating of a solar power system or why you might upgrade to a 24-volt system? If you are going with a system with more wattage, a 24-volt solar system with the same 24-volt battery bank system is suitable and will work for your load requirements.

With a 12v system, you can get 1000 watts equal to 83 amp, while in the case of a 24v system, you will get 2000 watts and 83 amp, which is doubled the power when compared with a 12v system. In another scenario, if watts remain 1000 in both 12 and 24 volts cases, you will get 83.33amp for 12volts and 41.66amp in the case of 24 volts, which is a huge difference. This means that the higher amount of amps will require larger wiring, and there would be a need for circuit protection components. The higher volume of amperes would require cables with larger diameters and high-capacity breakers, which would cost more bucks. So the good idea is to double the voltage of the inverter at the same level of current. You will get double the amount of power.

It’s wise to reduce the volume of amperes as high ampere values would likely melt the wires and are potentially dangerous as they can break out a fire.

Why Deep Cycle Systems for the 24v Inverter?

At Deep Cycle System, we use premium quality Phoenix Inverters available in 12v, 24v, and 48v. The Phoenix 24v inverter is known for its premium quality and is best for a wide range of applications. These inverters are designed to be compatible with home appliances by producing the true sine waveform that will increase the efficiency of electric appliances. Some of the key features of Phoenix inverters by Victron Energy are as under:

  • The ability to connect in parallel to up to 6 units increases the ability to get higher power output. This option is also available for a 3 phase setup.
  • The SinusMax technology provides extra power to start certain devices, including electric motors or compressors of refrigerators.
  • The battery safe mode is optimised to reduce high voltage fluctuations to stop any damage.
  • The system is designed to sense any voltage loss, possibly because of resistance or damage at the cable end.
  • The smart system is designed to sense any overcharge of solar batteries and can prevent any likely damage due to the overcharge of batteries.

Lithium Ferrophosphate (LFP) is a flame retardant, stable, safe and proven cell chemistry that has a very good energy density around 325 Wh/L. This cell chemistry can be engineered for various applications by adjusting the ratio of elements to provide high performance characteristics. E.g. the DCS marine battery range runs 2C cells, which means our little 75Ah battery will discharge comfortably at 75Ah x 2C = 150A. The DCS 80Ah Extreme runs 10C cells which means the 80A can comfortably discharge at 80Ah x 10C = 800A but is of course limited to lower currents due the the Battery Management System.

LFP also has very good cycling durability between 2,000 ~ 12,000 cycles can be achieved depending on how well the cells are managed, and the lowest rate of capacity loss (aka greater calendar-life) compared to other lithium cell chemistries.


Battery cells are simply a bunch of resistors with the ability to store energy. A 100Ah battery pack has a different resistance characteristic compared to a 50Ah battery pack, that theoretical difference in resistance is 2:1. So if you connect a 100Ah battery in parallel to a 50Ah battery there is no way for these two batteries to equalise and therefore you can’t charge them correctly. So for example connecting a 60Ah calcium starting battery to a 120Ah AGM via a VSR (Voltage Sensing Relay) you cannot charge both batteries correctly and from that day onwards you are prematurely destroying both battery packs. Same theory applies with lithium’s it’s still a battery pack.

What’s the solution? A DC-DC charger, you now have a permanent point of isolation (meaning that both batteries are never connected to each other in parallel). The DC-DC charger takes the surplus power from battery A (engine) and chargers battery B (aux/house). This device now allows any battery capacity and or chemistry to be used.

What if both batteries are the same, can I run a VSR between exactly the same two batteries?

Yes you can, but lithium’s have a different voltage curve, so you would still need to use a programmable VSR to dial them in correctly. However these devices draw a lot of power when engaged to so it’s best to run the two batteries in parallel and run a load disconnect instead of a VSR.

The advantages of the lithium battery cell chemistry

Lithium battery cells have a super low resistance so are very easy to charge and very efficient. This level of efficiency means you can charge them at very high C rates. For example if you look at the charge rate of a 100Ah AGM battery the recommended charging current will be around 25A, which is a 0.25C charge rate. If you consider the DCS 12V 100Ah Lithium battery it can be charged at up to 70A which is a 0.70C charge rate. This means you no longer need to consider DC-DC chargers as you can connect our batteries directly to high power charging devices such as suitable alternators, or large buck boosters. For example our popular dual 90Ah battery system for boats and 4WD vehicles, can be connected to alternators up to 160A.


Because our batteries are internally voltage regulated and because our BMS has such a high sustainable peak discharge current they will do an amazing job of equalising very quickly.


The BMS will open circuit the battery terminals to protect the cells. This means there is no longer any resistance in the system. The BMS needs a 12V signal with at least 1A of current to release and wakeup from a cell protection state. Most mains chargers with a lithium profile will do a slow recovery charge as will most solar regulators. Some chargers in the market today that are advertised as ‘lithium’ compatible still don’t have the firmware to do a slow recovery charge to release BMS’s. If you have a charger that will not wakeup the BMS, easiest way to wake it up is to connect a unregulated solar panel directly to the battery terminals, ensure all loads are disconnected before you do this. Having said that every system should have a suitable low cut off voltage to shutdown loads/accessories so that the batteries are not fully drained.


Use the following settings:

Charged voltage 14.0V
Tail current 4%
Charged detection time 1min
Peukert 1.05
Charge efficiency 98%
Current threshold 0.1A
C rates: refer to the battery pack capacity

What is the best state/charge to store these batteries ?

Fully charge to 100% isolate everything from the terminals and leave for max 3 months and then cycle (fully discharge and fully charge) and leave again for 3 months etc…. Minimum 4 cycles per year to not effect the cells capacity.
