Solar Inverters
PowMr offers a range of reliable inverters, which are categorized by 3 key characteristics:
Energy Sources, Grid Compatibility, and Enhanced Flexibility.
Power Inverters
The most basic inverter converts battery DC to AC. Suitable for RVs, boats, or basic standalone off-grid systems.
No
No
Single Phase
No
String Inverters
Solar inverters without batteries convert DC from solar panels into AC directly. Low initial cost, budget-friendly.
Yes
No
Single Phase
No
All in One Inverters
Inverter chargers combine MPPT solar charge controller, AC charging, and inverter, with programmable power priorities.
Yes (Dual MPPT Optional)
Solar Panel
Grid
Generator
Single / Split Phase
No
Hybrid Inverters
Manages power flow between PV, battery, and grid, enabling smart grid interaction for energy savings and gains.
Yes (Dual MPPT Optional)
Solar Panel
Grid
Generator
Single / Split / Three Phase
Yes
From All-in-One and Hybrid Inverters, additional options include:
Parallel Inverters
Account for future additions of panels or increased loads, choosing a parallel inverter that can scale with the system without replacement.
Low Frequency Inverters
Factor in appliances with high startup currents and prefer inverters with higher surge capacity, like low frequency types with large transformers.
Lithium Batteries
Our LiFePOâ‚„ batteries are offered in 4 main families to match power output and system size:
Low Voltage (12 V), Mid-Range (24 V), High Efficiency (48 V), and Industrial Scale (High Voltage).
