Product options and packaged configurations

Products built around measurable efficiency

Jemakor does not manufacture batteries. We help you choose and integrate components that create a dependable storage system: batteries, power conversion, protection, controls, and monitoring. This page outlines common product categories we specify and the performance questions that keep selection aligned to efficiency optimization rather than marketing sheets.

Compatibility first
Interconnection limits, inverter behavior, and protection design define what is feasible at your site.
Dispatch clarity
Control modes should be understandable by operators and verifiable in the meter data.
Safety-aligned
Enclosures, ventilation, and protection choices are planned for the environment and maintenance model.

Selection inputs

Checklist

If you are comparing vendors or configurations, these inputs prevent surprises and keep comparisons consistent. You can share them in a single message.

  • Service and interconnection: voltage, available capacity, export rules, and protection requirements.
  • Tariff details: time-of-use periods, demand charge method, and seasonal changes.
  • Load profile: interval data, peak kW drivers, and known process schedules.
  • On-site generation: PV size, expected production curve, and export compensation.
  • Resilience goals: critical loads, runtime expectations, and restart sequence needs.

Storage systems are engineered products with site-specific outcomes. Any projections should be reviewed against your measured load and operating constraints.

Product categories we specify

Product selection is about matching behavior to constraints. A high-capacity battery does not help if inverter power is undersized for your peak window. A fast inverter does not help if controls cannot enforce export limits or reserves. Jemakor typically specifies from established categories below, then validates the stack as a system: metering points, protection boundaries, and the controls needed to deliver your operating plan.

Each category includes typical evaluation questions so you can compare options consistently. When we assist, we document assumptions and propose acceptance tests that confirm the delivered system does what was intended at commissioning.

Battery modules and racks

Focus on usable capacity, cycle limits under your dispatch plan, thermal behavior, and serviceability. Confirm monitoring granularity and how the system responds to faults or temperature constraints.

  • Usable kWh and reserve strategy
  • Operating temperature range for site
  • Cell and rack-level monitoring access

Inverters and PCS

Evaluate continuous kW, short-term overload behavior, reactive power needs, and grid code support. Efficiency optimization often depends on power available during short peaks, not only nameplate ratings.

  • kW limits across SOC and temperature
  • Export control and anti-islanding
  • Reactive power and power factor modes

Controllers and EMS

Controls are where optimization is won or lost. Confirm available modes, scheduling options, and how the controller uses metering signals. Look for clear setpoints and auditable logs so operators can validate decisions.

  • TOU shifting and peak cap logic
  • Reserve settings for backup readiness
  • Data logs, events, and remote updates

Protection and switchgear

Protection defines what happens when things go wrong. Confirm breaker coordination, isolation points, and emergency shutdown behavior. For efficiency, protection should enable stable operation without nuisance trips.

  • Coordinated trip settings and selectivity
  • Lockout, E-stop, and service isolation
  • Export and backfeed constraints

Enclosures and thermal

Enclosures, HVAC, and ventilation affect usable capacity and longevity. Confirm temperature control strategy, filtration needs, and maintenance access. Efficiency declines quickly if thermal limits constrain power during peak windows.

  • Heat rejection capacity for the climate
  • Ingress protection and corrosion strategy
  • Service clearances and access panels

Monitoring and meters

Monitoring is how you prove optimization. Confirm meter placement, interval resolution, and who can access exported data. Reliable telemetry enables tuning and transparent reporting without manual spreadsheet work.

  • Site meter, PV meter, and storage meter plan
  • Exportable logs for verification and audits
  • Alarm thresholds and notification routing

How we evaluate product fit

Efficiency optimization starts with your load and your tariff, then works backward into equipment constraints. Jemakor evaluates product fit by translating your objective into dispatch requirements and confirming that each layer can safely deliver them. For peak shaving, the key is often instantaneous kW and control response. For self-consumption, it is usable kWh and scheduling. For resilience, it is a verified islanding path and a reserve strategy that does not conflict with daily shifting.

We also plan for operations. The most capable controller is not helpful if alarms are unclear or data exports are locked behind a platform. We prefer solutions where operators can see setpoints, view state of charge, and confirm charge and discharge behavior against the site meter. This reduces time-to-resolution when a system behaves unexpectedly.

Define dispatch targets

We identify charge windows, discharge windows, and the kW cap you want to enforce. Targets are expressed as setpoints and constraints, not vague goals.

Confirm safe operating limits

Temperature limits, state-of-charge guardrails, and protection coordination shape the maximum usable power and energy in real conditions.

Commissioning acceptance tests

Verification

A product choice is only proven after commissioning. We recommend acceptance tests that confirm the system delivers the intended control behavior, captures the right measurements, and fails safely. These tests also create a baseline for future tuning and maintenance.

Peak cap response

Induce a controlled peak and confirm the storage system holds site demand within the specified kW range without oscillation.

Schedule integrity

Validate TOU schedules across weekdays and weekends, including seasonal period changes, and confirm logs show setpoint transitions.

Meter and telemetry validation

Confirm interval resolution, correct sign conventions for import and export, and the ability to export data for independent review.

Fault and safe shutdown behavior

Trigger a non-destructive fault scenario and confirm the system isolates, alerts, and returns to normal operation only through defined steps.

Jemakor provides selection and integration support. Procurement, installation, and permitting are handled by your chosen vendor or contractor. If you request, we can review submittals and commissioning results for alignment to the operating plan.

Next step: align products to a real operating plan

If you already have quotes, we can help you interpret them against your intended dispatch. If you are starting from scratch, we can help translate your objective into a shortlist of configurations and the minimum metering and control features needed to verify performance. Either way, the outcome is a clear plan you can share with procurement and commissioning teams.

To keep the process focused, we ask for only the information required to respond: your name and contact details, site type, and a short description of what you want to optimize. Details you share are used to respond to your request and are handled according to our Privacy Policy.
