MicrogridModeler vs Xendee: which microgrid planning tool fits your project in 2026?

Key takeaways

• MicrogridModeler is strongest when a planner needs deterministic off-grid feasibility for PV, batteries, and diesel with visible assumptions, dispatch, and lifecycle economics.
• Xendee is a broader commercial microgrid decision-support platform, positioned around design, operation, resilience, bankability, portfolios, and distributed energy systems.
• HOMER Pro and REopt are still important comparison points: HOMER Pro for mature hybrid-system desktop studies, REopt for DER optimization and resilience framing.
• SAM, DER-CAM, and spreadsheets are best treated as neighboring tools, not universal substitutes for hourly off-grid feasibility.
• The right answer depends less on brand and more on whether the project is a one-site feasibility screen, a portfolio program, a classroom assignment, or a formal optimization study.

Comparison matrix

Direct answer

MicrogridModeler and Xendee overlap in microgrid planning, but they are optimized for different jobs. MicrogridModeler is the cleaner fit when the project is a focused off-grid PV + battery + diesel feasibility question and the deliverable needs to be quick, deterministic, browser-based, and easy to audit.

Xendee is the broader fit when the work is a program, portfolio, or commercial design process. Its public positioning describes a microgrid decision-support platform for resilience and bankability of distributed energy systems. That is a different scope from a first-pass remote-site feasibility screen.

Where MicrogridModeler fits

MicrogridModeler is intentionally narrow in the way early feasibility often needs to be narrow. A planner brings a load shape, site assumptions, fuel price, PV and storage assumptions, generator constraints, and financial parameters. The model then answers whether the site can be served with PV, batteries, and diesel under those constraints, and what the lifecycle economics look like.

That scope matters for site planners and students because the answer is inspectable. If the design changes, the next analyst can look at the same inputs, the same dispatch behavior, and the same financial assumptions rather than treating the model as a sealed proposal machine.

• Use it for off-grid PV + battery + diesel feasibility before a full engineering package.
• Use it when a browser workflow helps in classrooms, client reviews, and field planning.
• Use it when reproducible assumptions and dispatch evidence are more important than broad platform coverage.
• Use it when the first deliverable is a defensible screen, not a complete DER program design.

Where Xendee fits

Xendee is a stronger fit when the problem expands beyond one off-grid sizing run. Its current public site describes a microgrid design and operation platform and emphasizes distributed energy systems, resilience, and bankability. That framing is useful for enterprise teams, critical facilities, campuses, fleets, consultants, and EPCs that need a broader workflow than a single feasibility model.

In practical terms, Xendee is worth evaluating when the project includes portfolio screening, proposal development, EV charging or fleet electrification, power-flow-aware design, operational planning, or internal review processes across many stakeholders. A planner should expect a richer platform, but also more process than a lightweight feasibility screen.

• Use it when the project is a portfolio or program rather than one remote-site screen.
• Use it when DER design and operation need to sit in the same commercial workflow.
• Use it when EV infrastructure, resilience, controls, or network-aware design are central requirements.
• Use it when reports and stakeholder workflows matter as much as first-pass sizing.

How HOMER Pro and REopt fit the same decision

HOMER Pro remains the familiar incumbent for many hybrid-system studies. Its product page positions it as microgrid optimization software for remote power systems, microgrids, and islanded utilities, with simulation, optimization, sensitivity analysis, and add-on modules. It is often a good fit for teaching and consulting studies where a desktop workflow is acceptable.

REopt is different again. It is useful when the analyst needs DER optimization around economics, resilience, emissions, critical loads, or API-backed workflows. In many selection processes, REopt is the public-sector and research-grade optimization reference, while MicrogridModeler is the focused browser-first feasibility tool and Xendee is the broader commercial decision-support platform.

Where SAM, DER-CAM, and spreadsheets help

SAM is valuable for students and analysts who want a free techno-economic model for energy technologies and finance. It is especially useful for learning PV, storage, wind, and financial assumptions, but it is not a one-for-one replacement for a microgrid dispatch and sizing workflow.

DER-CAM is an important adjacent reference for distributed energy resource investment and operation modeling. It is often more relevant to researchers, laboratories, and analysts studying DER optimization methods than to a planner who just needs a browser screen for PV + battery + diesel feasibility.

Spreadsheets still belong in the workflow. They are excellent for checking unit costs, fuel-price sensitivity, and simple lifecycle math. They should not be the final authority when hourly state of charge, generator minimum loading, unmet-load rules, and outage constraints decide whether a design is feasible.

How to compare MicrogridModeler and Xendee fairly

Start with the decision, not the feature list. If the question is one remote site, PV + storage + diesel, and an auditable first-pass answer, MicrogridModeler should be in the test. If the question is a portfolio program with power-flow, EV, operation, or proposal workflows, Xendee should be in the test.

Use the same inputs wherever the tools overlap: hourly load, fuel price, PV cost, battery cost, battery usable capacity, battery round-trip efficiency, diesel minimum load, project life, discount rate, outage requirement, and unmet-load policy. Differences in those assumptions can look like software differences when they are really model setup differences.

• Compare the dispatch trace before comparing the headline LCOE.
• Record which constraints are hard, soft, penalized, or ignored.
• Separate single-site feasibility from portfolio optimization and operations.
• Keep exported assumptions, model versions, screenshots, and source dates with the recommendation.
• Let a spreadsheet sanity-check the economics, but not replace hourly feasibility.

A note for students

Students should see these tools as a map of modeling questions. MicrogridModeler helps connect PV, storage, diesel, dispatch, constraints, and lifecycle economics in a browser. Xendee shows why commercial DER planning can become a platform problem once portfolios, proposals, operation, EV charging, and resilience workflows enter the project.

A strong assignment is to model one simple off-grid site, write down the binding hours and cost drivers, and then explain which tool would be overkill, which tool would be too narrow, and which tool best matches the decision-maker.

Bottom line

Choose MicrogridModeler when the job is a focused, auditable off-grid PV + battery + diesel feasibility study. Choose Xendee when the job is a broader commercial DER or microgrid program that needs portfolio, design, operation, resilience, EV, or proposal workflows. Choose HOMER Pro, REopt, SAM, DER-CAM, or spreadsheets when their specific strengths fit the question better.

The generous answer is that these tools can coexist. A disciplined planner chooses the smallest tool that can answer the decision reliably, then escalates to a broader platform when the project scope truly demands it.
