ModX2

On-site electrical work is measured in hours rather than days. The system is factory integrated, pre-wired and tested before it leaves our facility, so there is no field integration to do. Installers have reported install-time savings of up to 70% against building an equivalent system from components.

A field-built equivalent typically occupies one or two licensed electrical workers for two to five days across mounting, wiring, controller configuration and troubleshooting.

The larger schedule item is usually not installation labour at all. It is structural certification, which runs 6 to 12 weeks and sits on the critical path before anyone can go to site. A pre-engineered platform removes that from the schedule, because the certification already exists.

Where site access is the constraint rather than labour, a possession window, a shutdown, a wet-season deadline, a compliance date, that schedule compression is generally the reason customers choose this platform over building their own.

No. ModX2 is an off-grid platform. It powers an isolated load at a site with no grid connection. It is not designed for grid-connected operation or for exporting power under a feed-in tariff.

If your site is already connected to the grid and you want to reduce bills or export surplus, that is a grid-interactive solar installation—a different product category entirely.

If your site has an unreliable grid and you need to keep running when it fails, talk to us about Vantara. It can be configured as a hybrid: running on grid when it is there, switching seamlessly to battery and generator when it is not.

We spell this out because specifying off-grid equipment into a grid-connected application creates a compliance headache after installation. Worth getting the category right upfront.

The fastest way to get to the right answer is to bring three numbers to the first conversation: daily energy consumption in kWh, peak and surge load in kW, and how long the site needs to survive with no generation. Everything else follows from those.

ModX2 is integrated, assembled and tested at Valen’s facility at Lawson, New South Wales, using componentry from established manufacturers. Valen Power is certified to ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018, and spares are held in Australia.

On a remote site four hours from a depot, Australian assembly buys you response time. A spare part dispatched locally instead of an import lead time. Support in your timezone. Warranty administration handled by the people who sold you the system, not routed offshore. And engineering support from the team that integrated the unit. That matters more than the flag on the paperwork.

Yes to both, with different degrees of effort. Battery capacity scales from one to three modules within the existing enclosure, so a site whose load grows, an extra camera, a comms upgrade, additional telemetry, can be uprated without replacing the system. Additional solar arrays are available as an option where generation rather than storage is the constraint.

Relocation is straightforward mechanically: the unit is designed to be lifted with batteries in situ, so a move is a crane, a transport permit and a new slab rather than a decommissioning exercise. That is a meaningful consideration for temporary construction, exploration and monitoring campaigns where the asset outlives the site.

Where relocation is the primary requirement rather than an occasional one, V-Trail is the better platform. It is trailer-mounted and designed to be towed and redeployed repeatedly.

The maintenance regime for a ModX2 is built around minimising site visits rather than eliminating them:

Two practical points matter more than the schedule itself. First, most of what a quarterly visual inspection used to catch is now visible remotely, generation trend, state-of-charge behaviour, alarm history and load drift all show up in the monitoring data, which lets you convert calendar-based visits into condition-based ones and cut the number of trips.

Second, keep the logbook. Where a warranty depends on evidence of correct operation, the service record and the monitoring log are the claim. Abnormal findings should be reported promptly, because a fault left running is a fault the warranty may not cover.

Two years on the full system and ten years on the batteries.

The distinction matters and is worth understanding rather than glossing. The two-year system warranty covers materials and workmanship across the integrated platform, enclosure, inverter, charge control, monitoring and wiring. The ten-year battery warranty reflects the service life expected of LiFePO₄ under the duty a remote monitoring load imposes.

As with any battery warranty, the conditions are what decide a claim. The ones to read: the ambient and cell temperature range the warranty assumes, the requirement to operate within the specified charge regime, depth of discharge limits, and what documentation is needed at claim time. Keeping the monitoring data and the service log is the single most useful thing you can do. It is the evidence file if you ever need it.

ModX2 is held in stock. Standard configurations dispatch within one week of order placement. Where a system needs customisation, allow up to four weeks.

Every unit is factory tested and fully documented before it enters stock. What arrives on site is a certified, commission-ready system, not components that still need work.

Where customisation is involved, the clock starts on design approval rather than on the purchase order. Returning the design approval promptly is the single biggest thing you control on the schedule.

For comparison, a component-built system requires structural certification before installation can begin, which alone runs 6 to 12 weeks. Where a project has a fixed compliance or possession date, that comparison is usually the decisive one.

Cost depends on battery capacity, wind region certification and options, so we size and price per configuration rather than publishing a single figure. To model your own site and get an indicative configuration, use the ModX2 calculator.

What we can be specific about is where the money actually goes on a remote power project, because that is usually the more useful answer. On a component-built alternative, the costs that surprise people are rarely the panels and batteries. They are:

• Structural certification, several thousand dollars and 6 to 12 weeks on the critical path
• Field integration labour, two to five days of licensed electrical work per site, multiplied across a rollout
• Integration troubleshooting when separately procured components do not communicate
• Battery replacements over a fifteen-year horizon, if the chemistry chosen cannot handle daily cycling, each one a remote site visit rather than a parts cost

For a multi-site programme, ask any supplier for cost per site at ten units rather than cost per unit at one. It changes the answer.

Supplied as an integrated, factory-tested unit: the solar array on its certified fixed frame, the LiFePO₄ battery modules, solar charge control, inverter and DC-DC conversion, the monitoring controller, and the stainless steel enclosure with 4RU or more of designated space for your own equipment. It arrives pre-wired and tested, with structural certification documentation.

Supplied by others, and worth budgeting for early:

• A level, certified concrete slab with chemical anchors. ModX2 mounts to a prepared foundation. Pre-engineered foundation designs are available as an option.
• The earthing electrode and its cable to the internal earth bar, targeting under 10 ohms.
• Site access suitable for a crane or lifting equipment. The unit lifts with batteries in place via integral lifting eyes, at a minimum 60° lift angle, and a spreader bar is recommended.
• Freight and delivery, quoted separately.
• Installation, connection and commissioning by a licensed electrical worker.

The weight of a three-battery configuration is approximately 480 kg, with overall dimensions of 2183 mm × 850 mm × 811 mm excluding the solar array. Confirm crane access and slab design against those figures before order.

ModX2 is supplied with monitoring through the Victron VRM portal, factory configured before dispatch. You get remote visibility of solar generation, battery state of charge, load, alarms and system events, over Modbus TCP/IP, Ethernet and a mobile app. Modbus TCP/IP integrates into an existing SCADA or network management system. The browser portal suits sites where SCADA integration is not wanted.

The operational case for monitoring on a remote site is straightforward truck-roll economics: a fault you can diagnose remotely is a scheduled visit with the right part, and a fault you cannot is two visits, one to find out what happened and one to fix it. On a site with a four-hour drive each way, that difference is the entire monitoring cost in a single event.

There is a second, less obvious argument that carries real weight with asset owners. Many battery warranties require evidence that the battery was operated within a controlled charge regime. Manufacturers commonly require proof that DC cells were operated in a controlled regime to honour warranty claims. Monitoring data is not just diagnostics; it is the evidence file for a future claim.

A pre-engineered off-grid solar power system is a solar array, battery storage, power conversion and control platform that is integrated, wired, tested and structurally certified as a single unit in a factory, then delivered to site as one product rather than assembled from separate components in the field. ModX2 is Valen’s fixed-frame version of that platform.

The distinction matters commercially, not just technically. A component-built remote solar system requires someone to size the array, select and match the controller and inverter, design a mounting structure, obtain structural certification for wind loading, and take responsibility when the pieces do not talk to each other. A pre-engineered system arrives with that work already done and documented, and with one supplier accountable for the whole system. For an unmanned site three hours from the nearest depot, single-point accountability is usually worth more than component-level cost optimisation.
