Off-Grid Inverter
DTSOLARPOWER supplies off-grid solar inverters for installers, distributors and system integrators working on remote power, battery-based solar and backup projects. This category includes compact inverter-chargers, MPPT-equipped models and selected higher-power units. Battery voltage, AC output and surge capacity vary by model.
An off-grid inverter creates AC power for local loads; it is not automatically approved to export electricity to the utility grid. Compare rated kW, output voltage and phase, battery compatibility, PV input limits and installation protection. For grid export or grid-interactive storage, review the separate on-grid and hybrid inverter ranges.

Off-Grid Inverter Product Range
Choose an inverter by its AC output, battery voltage and solar-charging configuration. Power ratings alone do not establish compatibility with a project.
| Model / Series | Power / Battery Platform | Selection Focus |
|---|---|---|
| Compact Off-Grid Inverter | 1.5 / 3 kW; 12 / 24 V variants | 220–240 V AC; integrated MPPT |
| Off-Grid Energy Storage Inverter | 3.5 / 5.5 / 6.2 kW; 24 / 48 V variants | Battery and PV-input matching |
| IP-Rated Off-Grid Inverter Series | DT-2KL1-US: 2 kW / IP21; DT-3K5L1-US: 3.5 kW / IP54; DT-08KL2-US: 8 kW / IP65 | Different AC output, enclosure and battery configurations by SKU |
| 5 kW Off-Grid Inverter | 5 kW; 48 V battery | Pure sine wave; check parallel operation |
| 6 kW Off-Grid Inverter | 6 kW; 240 V AC | Check PV Voc limit and MPPT start-up |
| 10 kW Off-Grid Inverter | 10 kW; 120/240 V split-phase | Surge capacity and battery sizing |
Specifications That Determine System Fit
| Specification | What to Check |
|---|---|
| Rated and surge power | Continuous loads, motor starting current and surge duration |
| AC output | 110–127 V, 220–240 V or split phase; frequency and wiring |
| Battery input | 12 / 24 / 48 V platform, charge current and battery chemistry |
| PV and MPPT | Maximum cold-weather Voc, MPPT range and charging power |
| BMS / AC charging | Communication protocol, generator input and transfer mode |
| Parallel capability | Supported unit count and synchronization requirements |
| Installation rating | IP protection, cooling, temperature range and service access |
Applications and Load Sizing
Cabins and Remote Homes
Match simultaneous loads, overnight battery demand and available PV charging.
Pumps and Workshops
Allow for motor starting surge, operating duty and protective devices.
Telecom and Backup
Check transfer time, generator support and required charging recovery.
Size inverter kW from simultaneous loads and starting demand; size battery kWh from expected operating hours. A higher PV rating cannot make up for insufficient inverter surge capability.
PV, Battery and AC Connections
A typical battery-based off-grid system uses an MPPT charger to manage solar input, a battery for energy storage and an inverter to power AC loads. The MPPT may be integrated or separate. Utility or generator input, where provided, does not automatically permit grid export.
Solar Array PV voltage and string design
MPPT Charger Integrated or external
Battery + BMS DC storage and charge limits
Inverter → AC Loads Continuous and surge power
Projects requiring grid export should use equipment approved for that purpose. Compare on-grid inverters or hybrid inverters for grid-connected applications.
Wholesale Enquiries and Documentation
Send the electrical requirements and intended installation environment for model selection. Request a datasheet, installation manual and compliance documents applicable to the selected SKU and destination market.

Off-Grid Inverter FAQ
-
How does an off-grid inverter differ from a hybrid inverter?
Off-grid units supply local loads independently of the grid. Hybrid inverter grid and backup functions depend on the specific model and certification.
Close answer ↑ -
Can an off-grid inverter operate without a battery?
Some models can operate from PV without a battery; others require battery power. Check the exact inverter operating modes.
Close answer ↑ -
Should I choose a 24 V or 48 V inverter?
Match the inverter input to the battery bank, cable sizing, charge current and BMS. A 24 V battery cannot connect directly to a 48 V-only input.
Close answer ↑ -
How much surge power does a water pump need?
Use the pump motor's starting current and start method to calculate demand, then compare it with the inverter's surge rating and duration.
Close answer ↑ -
Do all off-grid inverters include MPPT?
No. Confirm whether an MPPT controller is built in and check its PV voltage, power and charge-current limits.
Close answer ↑ -
Which models have IP21, IP54 and IP65 ratings?
In the linked series, DT-2KL1-US (2 kW) is IP21, DT-3K5L1-US (3.5 kW) is IP54 and DT-08KL2-US (8 kW) is IP65. Installation requirements still depend on each manual.

What information is needed for an inverter quotation?
Provide AC load, starting surge, PV and battery details, destination, quantity and installation requirements.
