Quantity:This more substantial system features 940W of panels and can generate up to 747kWh per year in the UK or 1292kWh in southern Europe. Great for club houses, welfare units, small houses and much more.
Based on four of our best-selling MCS-accredited Romag Powerglaz 225W solar modules and the high-performance Morningstar Tristar MPPT 45A regulator, this system has a 250Ah @ 24V battery capacity to keep you going when the sun is not shining.
A top-of-the-range Mastervolt 1.5kW pure sine wave inverter will power plenty of small and medium appliances such as lighting, radios, computers, power tools etc. A sophisticated battery monitor is included so you can keep an eye on the system status.
For the UK market, the system components meet MCS standards. If you are opting for a feed-in tariff eligible installation you will require some additional components and the system must be installed by an accredited electrician. Please contact us to discuss your requirements or for any advice on MCS accreditation for off-grid PV installations.
The system comprises:
- 4 x Romag Powerglaz 225W solar panels
- Morningstar TriStar 45A MPPT regulator
- 4 x 125Ah Elecsol carbon fibre batteries
- Mastervolt 1500W 24V Mass Sine inverter
- NASA BM1 24V battery monitor
- Battery harness, terminals and covers
- All necessary cabling, fuses and switches
- Optional panel roof mounting hardware (please select from menu above when ordering)
This system is suitable for DIY installation if you are not opting for feed-in tariffs. We are happy to advise on details of the installation process, but the basic steps are:
- Mount the solar panels. (Please ask us for the optimum orientation and aspect)
- Fix the main board to a wall, somewhere cool, dry and secure
- Connect the inverter to your AC wiring and earth
- Lay out the batteries and fit the wiring harness
- Connect the batteries and panels to the main board
- Switch on and enjoy!
Full instructions and documentation will be provided with the equipment.
We have tried to make this system as simple to install and as safe as possible. Safety features include DC fuses and disconnects. But if you are in and doubt whatsoever consult a qualified electrician.
The system in use
The battery meter will give a constant display of battery voltage, current in or out of the batteries and an estimation of their state of charge. Generally speaking, you should try to keep the batteries above 24.4V at all times (roughly 40% on the state of charge meter).
If the battery voltage falls to 19V the inverter will automatically cut off output to prevent damage until the battery voltage is restored to at least 22V If this happens, be sure to let the batteries recover to at least 75% charge (approx 25.2V) as soon as possible to prolong their life.
The regulator has 24V output terminals with an automatic low-voltage cut off - this is ideal for running 24V appliances that are always left on, for example a fridge or an external light on a motion sensor. These terminals can supply up to 45A at 24V, but you can also connect your 24V appliances direct to the commoning points on the main board if desired. Use an appropriate fuse and note that 24V consumption will not be metered, and hence you will not receive the feed-in tariffs for this proportion.
The inverter features automatic power saving mode, and can be safely left permanently switched on. As a pure sine wave inverter, it can be used to power any equipment up to the maximum output of 1500W just as smoothly and effectively as mains electricity. An optional remote control panel is available for this inverter.
